19.01.2024, Friday

They called us to school once again to 'practice' for physics and bio practicals which are in the first week of Feb, I don't think much 'practicing' happened but we did get some core points to focus on while preparing. I'm a little apprehensive about physics because it's been months since I've done any of the experiments but I've always been good at practicals so I think I'll manage. I want to finish my math and physics revision before practicals week because I barely have any time after that. I'm leaving chem for last because I will definitely want to procrastinate chem and I can't afford that right now so I'll do it last with the pressure of the deadline on me so that I refrain from procrastinating. I've been getting more and more nervous about the theory exams as the days progress and I don't want to think about them right now. I'm practicing each chapter individually and then doing previous years papers and sample papers during the revision time I don't know if that'll be enough but I hope it is. Didn't get to study much today but I did finish the second half of this chapter, I love matrices and determinants they're the easiest thing in the whole book.

Time Studied: 3 hours Subject: Mathematics Content: Determinants

Yes, Master - Chapter 3

Chapter 1 | Chapter 2 | Chapter 3 | Chapter 4

Summary: Alastor X reader, F/M. Alastor fucks you silly

Warnings: vaginal penetration, BDSM, Dom/sub. This story is 18+, minors can fuck right off.

Other Notes:

Darby Link Tree

Chapter 3: So Willing

“This might hurt, darling.” 

Alastor entered you, hard, in one thrust. You gripped the bedding as you cried out. He dug his claws into your hips as you clenched around his girth, small lines of red ran down your thighs from the punctures. He stayed there a moment as he gripped you against him, feeling your tight wetness twitch against his intrusive cock. 

“Thank you, Master..” you whimpered into the blankets.

“That’s my good girl, so willing,” he growled.   

His hand caressed your lower back as it slid down between your shoulder blades. He leaned forward, placing his body weight onto you and forcing the breath from your lungs. You turned your head to the side in hopes of accessing more air than the bedding provided. His pelvis pushed your hips forward, bending your back, and pushing your ass up. The position dug is erection deeper inside of you. It only allowed for short but harsh thrusts. Wincing with each slap of skin on skin. Your claw punctured the matrice.  

“What is your purpose?” He asked.

“To plea..se you, ..Master,” you moaned. 

“And you do pet, such a good little cock sleeve, taking all of me like this,” he praised. 

“Mhhmmuh, fuck…” He thrust aggressively into you, bottoming out each time. You thought you might choke on the saliva pooling in your mouth. “Ugahhhghh.. Please… Master… it's too much..” 

“You’ll take whatever I give you.”

“Y.. ye..s, Mast..er, hhmmgggh…”

Alastor had said something in response but your brain was starting to feel like mush, you heard the individual words but couldn’t quite comprehend them. The head of Alastor’s erection was using your cervix as a punching bag. Each squelching slap of his thrusts drove you closer to climax. You groaned as your walls clenched down on him, legs shaking. Alastor growled as he removed his weight from you, dragging his claw down your back. 

“That’s my girl,” he let your orgasm ride out before he pulled out of you. “Roll over, pet.” 

When you didn’t respond Alastor lifted you up, arm around you, and flipped you over onto your back. He grabbed your throat and pulled your face close, ready to scold you. Your eyes were teary and glazed over. Drool was smeared on the edges of your slacked jaw. You mumbled as you feebly reached for him.

“Oh, sweetheart, you can’t hear me, can you?” He combed the hair out of your face with his claws. “I’ve fucked you stupid, poor thing.”

He hummed, pleased with your mental state. He laid you back into the pillows gently. His tongue licked the drool from your face before assaulting your mouth. Your brain registered the interaction and attempted to reciprocate. He entered you again with ease. Placing your legs over his shoulders, he leaned in and folded you. His thumb caressed your bottom lip as his pelvis pounded your soaked groin. Salty lines ran down your cheeks. The tension was already building again, your eyes fluttered as you came. Alastor hissed as you gripped him once more, he placed his forehead on yours, breathing heavily. 

“Let’s see if we can get one more out of you before I fill you, hm? You’ve been so good for me pet, a perfect little fuck doll.” 

The most you could manage was a small hum. The praise made your head swim. He dropped your legs, wrapping them around his waist. He sunk himself into you, softer this time. His hand ran through your hair as he whispered in your ear.

He buried his face in the crook of your neck, his warm breath tickling your skin with each grunt. Alastor slowly dragged in and out of you, stimulating your already sensitive tissues. Your legs tightened, pushing him deeper into you as his teeth sunk into the flesh of your neck. His tongue outlined each puncture, collecting the dribbles of blood. You exhaled a whimper. 

“Mine…” he growled as he held your head. He nuzzled into your hair, taking in your smell. “No one else will ever have you like this.” 

You were desperately holding onto consciousness. You wanted your Master to come inside you, to show you how pleased he was with you. It was the only thought in your head. Your legs were so weak, yet they still shook as you came. Alastor purred in approval.

“That’s it, pet, cum on your Master’s cock.” 

“Pl…ea..s…e … Mast..er…” You were so exhausted, were your words even loud enough to hear? “Please…..cum in me” 

“Anything for my good girl.”

Soil Science 2/24

Okay, this is a class I struggle a lot with. I am taking this class instead of chemistry or physics, but I am personally not interested in the topic at all. I think my professor is very smart and my lab TA is awesome, but I cannot get into the content. Hoping this blog will save me a little bit.

Lets talk about some soil water. Since I started this blog a little late into the semester, you are going to be learning about the last segment of this chapter.

Unsaturated flow:

Flow is determined primarily by matric potential

matric potential measures how loosely the water is held (positive values means water moves easily, negative values mean water is held tightly)

its essentially the stickiness of water to soil particles

low matric potential is dry (negative numbers), high matric potential is wet (positive numbers)

Water moves from areas where it is loosely held -> areas where it is tightly held

Infiltration: process by which water enters the soil pore space and becomes soil water

Infiltration capacity: rate at which water can enter the soil

infiltration is not constant overtime

it is dependent on the soil texture and structure

quick in dry soil

slow as clays are hydrated

Percolation: movement of water downward

due to both saturated and unsaturated flow

Wetting front: where wet soil meets dry soil as water moves through a soil

due to matric potential and gravitational potential

Unsaturated flow through a profile:

From coarse to fine:

DOWNWARD: water goes through coarse, but at finer texture percolation slows and lateral (sideways) water movement increases

UPWARD: if there was enough capillary action, the fine texture would keep pulling water up through the coarse until it was saturated

(capillary action: ability of water to move upward due to attraction to itself and solid surfaces)

From fine to coarse:

DOWNWARD: water will not move into coarse until fine is full

UPWARD: water will not move into coarse until fine is full

This is all I have for today, we had barely anything left in the chapter, and honestly she moved on to the next unit even though our exam isn't until Friday and it made me mad so I just started playing HayDay on my iPad. I did know all of the answers to the quiz without having to check my notes today, so I do want to share that little accomplishment!

I want to try to post daily, so on weekends I may blog about my social life, my studying, or maybe even my job if I feel like it

Basics of R programming

Understanding the basics of R programming is crucial for anyone looking to leverage its capabilities for data analysis and statistical computing. In this chapter, we'll explore the fundamental elements of R, including its syntax, variables, data types, and operators. These are the building blocks of any R program and are essential for developing more complex scripts and functions.

R Syntax

R's syntax is designed to be straightforward and user-friendly, especially for those new to programming. It emphasizes readability and ease of use, which is why it's popular among statisticians and data scientists.

Comments: Comments are used to annotate code, making it easier to understand. In R, comments begin with a # symbol:# This is a comment in R

Statements and Expressions: R executes statements and expressions sequentially. Statements are typically written on separate lines, but multiple statements can be written on a single line using a semicolon (;):x <- 10 # Assigning a value to variable x y <- 5; z <- 15 # Multiple statements in one line

Printing Output: The print() function is commonly used to display the output of expressions or variables. Simply typing the variable name in the console will also display its value:print(x) # Displays the value of x x # Another way to display x

Variables in R

Variables are used to store data values in R. They are essential for performing operations, data manipulation, and storing results.

Creating Variables: Variables are created using the assignment operator <- or =. Variable names can contain letters, numbers, and underscores, but they must not start with a number:num <- 100 # Assigns the value 100 to the variable num message <- "Hello, R!" # Assigns a string to the variable message

Variable Naming Conventions: It’s good practice to use descriptive names for variables to make the code more readable:total_sales <- 500 customer_name <- "John Doe"

Accessing Variables: Once a variable is created, it can be used in expressions or printed to view its value:total_sales <- 1000 print(total_sales) # Outputs 1000

Data Types in R

R supports a variety of data types that are crucial for handling different kinds of data. The main data types in R include:

Numeric: Used for real numbers (e.g., 42, 3.14):num_value <- 42.5

Integer: Used for whole numbers. Integer values are explicitly declared with an L suffix:int_value <- 42L

Character: Used for text strings (e.g., "Hello, World!"):text_value <- "R programming"

Logical: Used for Boolean values (TRUE or FALSE):

is_active <- TRUE

Factors: Factors are used for categorical data and store both the values and their corresponding levels:status <- factor(c("Single", "Married", "Single"))

Vectors: Vectors are the most basic data structure in R, and they can hold elements of the same type:num_vector <- c(10, 20, 30, 40, 50)

Lists: Lists can contain elements of different types, including vectors, matrices, and even other lists:mixed_list <- list(num_value = 42, text_value = "R", is_active = TRUE)

Operators in R

Operators in R are used to perform operations on variables and data. They include arithmetic operators, relational operators, and logical operators.

Arithmetic Operators: These operators perform basic mathematical operations:

Addition: +

Subtraction: -

Multiplication: *

Division: /

Exponentiation: ^

Modulus: %% (remainder of division)

Example:a <- 10 b <- 3 sum <- a + b # 13 difference <- a - b # 7 product <- a * b # 30 quotient <- a / b # 3.3333 power <- a^b # 1000 remainder <- a %% b # 1

Relational Operators: These operators compare two values and return a logical value (TRUE or FALSE):

Equal to: ==

Not equal to: !=

Greater than: >

Less than: <

Greater than or equal to: >=

Less than or equal to: <=

Example:x <- 10 y <- 5 is_greater <- x > y # TRUE is_equal <- x == y # FALSE

Logical Operators: Logical operators are used to combine multiple conditions:

AND: &

OR: |

NOT: !

Example:a <- TRUE b <- FALSE both_true <- a & b # FALSE either_true <- a | b # TRUE not_a <- !a # FALSE

Working with Data Structures

Understanding R’s data structures is essential for manipulating and analyzing data effectively.

Vectors: As mentioned earlier, vectors are a fundamental data structure in R, and they are used to store sequences of data elements of the same type:numbers <- c(1, 2, 3, 4, 5)

Matrices: Matrices are two-dimensional arrays that store elements of the same type. You can create a matrix using the matrix() function:matrix_data <- matrix(1:9, nrow = 3, ncol = 3)

Data Frames: Data frames are used for storing tabular data, where each column can contain a different type of data. They are akin to tables in a database:df <- data.frame(Name = c("John", "Jane", "Doe"), Age = c(25, 30, 35))

Lists: Lists are versatile structures that can store different types of elements, including other lists:my_list <- list(name = "John", age = 30, scores = c(90, 85, 88))

What are the Important Topics for JEE Mathematics? 

JEE Maths is the subject that most JEE applicants are concerned about. It entails complex concepts, but it also necessitates a significant amount of labour to solve multiple problems. Remember one word if you want to achieve in JEE maths: PRACTICE!!! If you want to enhance your JEE maths and get good grades, you should spend more time-solving problems than reading theories, equations, and answers.

You should be able to solve the tasks with ease. You can improve this by putting in a lot of practice time before the exam. Be tenacious in your pursuit of knowledge, and learn something new every day. JEE Maths questions also assess your ability to focus on a problem and find an answer swiftly. Many people lose up in the middle of a question because they believe it is too long or difficult. That is not something you should do. The JEE Maths paper is never too complicated or lengthy, and there will be students who score higher than 95% on the same paper as you, so why not you?

Important Topics for JEE Mathematics

Don’t recommend solutions without first trying them out: With all of the JEE Mathematics books and study materials available, most students tend to read a question and quickly look for the answer. This is entirely incorrect, and if you continue in this manner for an extended period, you will get reliant on solutions and create a poor habit of yielding. In JEE Maths, on the other hand, you must have a battling mindset. Try your hardest to figure out the trick. We understand you don’t have much time to spend on each question, but at least 60-70 per cent of the time, you should try the question yourself first (spend 10-15 minutes on average on each question) before consulting the solution. It is critical to attempt initially since your brain develops only when you put it under stress.

Important Maths Chapters for JEE: From the standpoint of JEE, some chapters are pretty crucial. Integrals, 3-D Geometry, Probability, Conic Section, Vector Algebra, Functions, Limits, Continuity & Derivability, Matrices & Derivatives, Probability, Permutation, and Combination are among the chapters covered. These chapters could account for up to 65-70 percent of your final grade.

Important JEE Maths chapters and strategies for mastering them: Quadratic equation, Trigonometry, Inverse Trigonometric Functions, Permutation and Combination, Circle, Binomial theorem, Sequence and Series are all crucial chapters for JEE.

The NCERT Mathematics books include all of the necessary information as well as basic and easy questions. They aid in the formation of a solid intellectual foundation and the development of confidence. As far as Jee Main is concerned, this is more than enough. You can go on to advanced problems if you’ve mastered all of the fundamentals.

Make sure you review the formulas for Coordinate Geometry from a credible source. The ideal method is to write them all down on a piece of paper and modify them regularly. Only by putting them into practice can you learn them. As a result, try to solve as many issues as you can.

Take a notebook and jot down all of the formulas, identities, and so on for trigonometry. Examine the notebook you’ve kept daily and make sure it’s up to date. Pure questions of trigonometry are uncommon in JEE Maths, according to the recent pattern of questions. However, some Trigonometry knowledge may be required for topics using Calculus, Coordinate Geometry, Sequence, and Series. As a result, it is preferable to go over the complete formulas and get some practice from RD Sharma.

If you understand the basics of calculus, pick any publication book, such as Arihant Publications, and begin tackling the problems. It is not true that if you solve 100 questions in Calculus, you will solve any issue in that area. For that, you must solve a large number of issues.

Permutations and Combinations, and Probability are two JEE Maths topics in which you must first use your head before using mathematics. Converse will almost always land you in serious trouble. Begin by giving an overview of what the question is asking; for example, if it asks about grouping theory, that particular formula should come to mind. After that, put mathematics away for a moment and think about it as if it were a real-life situation. Start by applying mathematics if you’ve considered what you’d do to solve the problem. By following all the topics it can a student weak in maths crack IIT.

It assists students in identifying their deficiencies by supporting them in preparing for JEE through real-time interactive IIT JEE sessions. They offer adaptive courseware that allows you to learn at your speed.

hey lia, hope you're having a good day !

sorry if i'm bothering too much. i saw your recent anon post bout jee and i had to ask this. i genuinely do not care for maths. like that subject loathes me, no matter how much i try i just can't get it. and i have seen people score 90+ without solving any math questions and i was wondering if i could skip it too as a pcm student? like it's only gonna bring my score down anyway so why not just leave it un attempted? or maybe focus on the important high weightage chapters only? can we do that? also can you tell me the high weightage chapters?

AND i'd loooooove if you spill some secrets on how you do maths only if you don't mind obv.

love ya <3

hii, i hope you're having a good one too and oh no please it's never a bother, you can reach out to me anytime, never a problem <33

alrighty so let's get to the issue, so you see, this was me last year like i was struggling with math and had almost given up on it and whereas it does seem like a cool idea, personally i'd not suggest you to leave it out as a whole, like getting 12 marks in maths which is like 3 questions might boost your score by a LOT.

i literally have no secrets, it's just that i focus on the chapters i know i can solve like, okay to answer your question, high weightage chapters are, vector algebra + 3d, integral calc, sequence and series, binomial theorem, matrices and determinants.

now let's say i focused on the high weightage chaps and practiced integral calc, but then a tough question came in the exam, which is highly likely because calc isn't easy, so i'd have to leave it nonetheless, hence i'd suggest you to focus on easier chapters and it'd differ for me and you, like if i find pnc easy and you don't, and you find aod easy but i dont, so we do the chapters we find relatively easier, i know math might seem scary which it is, for sure, but leaving it completely would put all the burden on physics and chemistry and how the recent trend for the exam was, it'd be tough.

love you too, hope it helped, don't shy away from reaching out, mwah! <3333

all in all i'd suggest you to focus on the chapters you find easy, if you find integral calc tough,don't do it, invest that time in a chapter you're comfortable with so that you solve the question if it comes in the exam! (also like choose the chaps like stats or probability, which cater to similar type of questions)
