Maths is next! I love doing maths but the syllabus is too huge. We need to complete revising 12 chapters. But we also have a long gap of 5 days. So far I have completed revising 6, 6 more to go! Recently I have started following James Scholz from YouTube. Although after the 11.5 hrs he studies, when it ends, I become completely burnt out (which is generally not the case when studying alone), I have started to enjoy studying with him. It’s less distracting and I have a structured schedule about when to take a break and when to study. Hope I do good in maths!

Things I did today-

Study theory of Permutation and Combinations

Practice solving problems on PnC

Studied theory of Binomial Theorem (I literally forgot everything about it. Took up a huge chunk of my time)

Practice solving problems on Binomial Theorem

Revise the formula of Trigonometry

________________________________________________________

PS- I am going to my Bio tuition after an entire month. I was suffering from pox for which I didn’t go there for 2 weeks and then the exams on the exact class timings prevented me from going for another week. I missed 2 tests and my teacher once asked my mom about it. Although she was told by my mom I had pox and I was absent, it’s kinda scary to go again today. She already removed 7 people from the group chat coz they didn’t attend for a week. I am absolutely fucked I think.

Guide to High School Tutoring Services for Year 11 and 12 Success

High school tutoring services are nowadays becoming quite important due to increased competition among students to perform better in academics in HSC exams. When it comes to the biology subject, the syllabus is structured to develop students’ understanding of biology as a science, focusing on core topics such as cells as the basis of life, genetic inheritance, and ecosystem dynamics in Year 11. When students progress to Year 12, the syllabus delves deeper into heredity, biological diversity, and contemporary biological advancements.

Similarly, maths is another crucial subject that many times students find difficult to grasp due to insufficient understanding of the basics. Maths tutoring in such cases becomes very crucial and in the Year 11 advanced course, one understands deeply concepts like differentiation, functions, further differentiation, and trigonometry. Also, practice is quintessential for subjects like maths as one needs to try out exam-style questions to get the best results. With mock exams, one not only practices the right questions but also gets the real feel of an exam and hence this makes one more comfortable to face the real exam.

Mathematics is not just about learning formulas as this will not be enough to score well in exams rather one must be well-versed in the proper layout of proofs and mathematical work to score well in exams. Similarly, physics is another subject that requires not just memorising the concepts but also a deeper understanding of the fundamentals for getting the best results in exams. For the HSC exams of physics, one must prepare themselves well in both Year 11 and Year 12. The Year 11 syllabus consists of units of kinematics, mechanical waves, dynamics, non-mechanical waves, thermodynamics, and electricity and magnetism.

In Year 12 physics the syllabus consists of advanced mechanics, electromagnetism, the nature of light, and from the universe to the atom. Both the years’ courses offered by leading tutoring centres have 11 weeks of tutoring and also there are exams at the end to get the students familiarised with the exams.

The leading HSC tutoring centres have the best results when it comes to HSC exams. Get in touch with the leading tutoring centres for your child enrolled in tutoring classes for Years 7, 8, 9, 10, 11, or 12.

How to Prepare for JEE (Joint Entrance Examination)

The Joint Entrance Examination (JEE) is one of the most competitive exams in India, required for admission to top engineering colleges like IITs, NITs, and IIITs. A well-structured approach, dedication, and a clear understanding of key concepts are crucial for cracking this exam. If you're preparing for the JEE, here is a comprehensive guide to help you succeed.

1. Understand the Exam Structure

The JEE is conducted in two stages: JEE Main and JEE Advanced.

JEE Main: It is the first level and is required for admission to NITs, IIITs, and other centrally-funded technical institutions. It also serves as a qualifying exam for JEE Advanced.

JEE Advanced: This is the second level, and qualifying in this exam opens the doors to prestigious IITs.

Both exams focus on three core subjects:

Physics

Chemistry

Mathematics

Familiarizing yourself with the syllabus and exam pattern is the first step in understanding how to effectively prepare.

2. Build a Solid Foundation of Concepts

The key to success in JEE is conceptual clarity. The JEE tests your understanding of the fundamentals rather than rote memorization. Therefore, focus on strengthening your basics in Physics, Chemistry, and Mathematics from Class 11 and 12.

Recommended books include:

Physics: H.C. Verma’s Concepts of Physics and I.E. Irodov for advanced problems.

Mathematics: R.D. Sharma for basic understanding and books by S.L. Loney for Trigonometry and Coordinate Geometry.

Chemistry: O.P. Tandon for Physical and Inorganic Chemistry, and Morrison & Boyd for Organic Chemistry.

3. Create a Study Schedule

Consistency is key to cracking JEE. Create a detailed study plan that includes daily, weekly, and monthly goals. Break down your syllabus into smaller chunks and allocate time for each subject based on your comfort level. Ensure that you balance between:

Learning new concepts: Cover new topics in-depth.

Revision: Regularly revise older topics to retain information.

Practice: Solve problems every day to test your understanding and improve speed.

4. Practice Regularly and Take Mock Tests

Solving a large number of problems is essential for JEE preparation. The more problems you solve, the better you’ll be at tackling tricky questions during the exam. Start with easy problems to build confidence, and then move to more difficult ones.

Additionally, take regular mock tests to simulate the actual exam environment. Mock tests will:

Familiarize you with the exam pattern.

Help you develop time-management skills.

Allow you to analyze your weak areas and improve on them.

Platforms like NTA Abhyas and Aakash iTutor provide mock tests that closely mimic the actual JEE exam.

5. Focus on Time Management and Accuracy

JEE is not just about solving problems, but solving them quickly and accurately. During preparation:

Time each question: Get used to solving problems under timed conditions.

Skip tough questions: If you’re unable to solve a problem within 2-3 minutes, move on and revisit it later.

Avoid negative marking: Be mindful of the negative marking system in JEE Main and JEE Advanced. Guess only when you’re reasonably sure.

6. Revise Regularly

Revision is essential, especially for topics you’ve covered earlier in your preparation. Make short notes while studying, especially for important formulas, concepts, and reactions. These notes will help you quickly revise before the exam.

Here are a few revision tips:

Weekly Revision: Set aside one day each week for revising the topics you've covered.

Flashcards and Mind Maps: Use these tools to reinforce key concepts and formulas.

Solve Past Papers: Solve previous years’ JEE papers to familiarize yourself with the types of questions asked.

7. Stay Healthy and Stress-Free

JEE preparation can be intense, but maintaining your mental and physical health is critical. Here are some tips:

Take regular breaks: Studying for long hours without breaks can lead to burnout. Take short breaks after every 1-2 hours of study.

Exercise and Meditation: Physical activities and meditation can help reduce stress and improve focus.

Sleep: Ensure that you get at least 7-8 hours of sleep daily to keep your mind fresh.

8. Seek Help When Needed

If you find any topic or concept particularly difficult, don’t hesitate to seek help from teachers, friends, or online resources. Joining a coaching institute can also provide structured guidance. Some popular JEE coaching centers include Allen Kota, FIITJEE, and Resonance. Alternatively, there are numerous online platforms like Unacademy and BYJU’s that offer quality study material and live classes.

9. Stay Motivated and Positive

Finally, JEE preparation is a long and challenging process. Staying motivated throughout the journey is crucial. Keep reminding yourself of your goals and the reason you started. Surround yourself with positive influences, stay disciplined, and have faith in your preparation.

ON MATH ANXIETY

When I was a kid, my parents and relatives thought that I was a math prodigy, a brilliant, bright child who excelled mostly in math and science. Disclaimer: This was during kindergarten. Then we were introduced to addition, subtraction, multiplication, and division. It feels like life keeps falling apart for a 6- to 12-year-old kid. I was at the top of the class during my childhood years. And when PEMDAS becomes more complicated, including the operation of fractions, I feel lost every time I look at the board or at my notebook.

Then, when I entered high school, the first math that I encountered was algebra. When negative numbers were introduced, I was like, 'What the hell was that? '. Then exponents, square roots, fractions of square roots, exponentials, logarithms, cartesian plane, and WE ARE LITERALLY SOLVING LETTERS WITH NO NUMERICAL ANSWERS.

I did what most teens did during that time: cut class, go in the class drunk (sometimes high), and I already accepted that I couldn't excel. Whatever I do, I can't bring myself to my fullest. Especially when I received my grade in algebra, 71 (on the first quarter) ~ if I remember it correctly. My grade in Science I (Earth Science) was 76. I was labeled slow. Oh, when the overall ranking came out. Out of 74 students in our section, I was placed on the 70th. I was like, 'Oh, yeah. Whatever'. Then my friends and I just laughed about it. There is a reason for the continuous decline in the academic performance of a 13-year-old teenager, either within themselves or with their surroundings. Especially when you can't determine what the most suitable action is to take. It is a fight-or-flight response.

I was required to attend summer classes before since I failed most of my subjects, especially math and sciences. Biology came, chemistry hindered the way, and lastly, physics was the last straw. This is for science alone. For math, on the other hand, algebra, geometry, trigonometry, and statistics made me realize that I would not learn mathematics.

It made me anxious; most of the time, I throw up whenever we have major examinations. But those days were already over. I brought this up during my undergrad and graduate years. We can be anxious. But we are not our anxiety; we are not our emotions. And like most things, this can be let go. It will fade eventually.

I overcome this fear by simply 'trying'. Try and try. So during the 3rd year of my college years, I decided to face all these fears of mine. I faced an empty sheet of paper, holding a pen, with a formula sheet beside my answer sheet. I solve. I continued this until I grasped the process. What I realized along the way is that I don't have the strategy to study. It took me years to study in advance. I don't have the right resources and materials. And during that time, whenever I studied one subject, I used 4–6 books. I compare how each book discusses the topics. And when there is something that I don't understand, I go directly to my instructors. I always make sure that I have the right person to ask.

Acknowledging your feelings (your fear and math anxiety) is the first step in conquering them. Your instructors can help direct you to good resources and practices that can help you reduce or eliminate the emotional blocks to learning math and physics.

It will make you stronger and will help you find the most effective way to overcome your fear/stress/anxiety not just in math but with real-life problems that you might encounter along the way.

How does middle/high school work, what's it like and what's the difference between the two? I really need some help! (I know this is a weird question but I was homeschooled most of my life so I have no idea how middle/high school work and what's it like.)

No problem!

How to Write About Middle School/High Schools

Middle school and high school are key times within a child’s life.

Gone are the days where they only had one teacher to tell them everything; now they have to change classes and have harder content that they have to study.

There’s more friend drama now that they’re all developing their own identities and their sense of who’s a good person and who’s not, and along with that comes astronomical stress compared to their elementary school years.

There’s also puberty, which sucks, and the beginnings of serious extracurricular activities that require a lot of time and dedication.

*This may vary from school to school*

Middle school = Grades 6-8 (Kids 11 to 13)

High school = Grades 9-12 (Kids 14 to 18)

Since many people have no idea how to write about schools, whether they be homeschooled or have graduated a while ago, here’s a few tips on how to write middle school and high school.

Just a note that I’m going to be describing public schools and not private schools, Also, schools are going to be different across the country; I’m a New Yorker, and my school knowledge and experience can be way different than those of someone who went to school in the south or in the midwest.

**IMPORTANT NOTICE!**

“High school” and “middle school” are not capitalized! Only capitalize it when you’re saying the name of the school. (Example: Eldridge Middle School)

1. Know What Grades Take Which Courses (AKA Know All the Technical Stuff)

Nothing demonstrates complete lack of knowledge about the school system than not knowing the basic technical side of it, such as which grades take which classes. Aside from various exceptions, an eighth grader isn’t going to be taking Physics and a twelfth grader isn’t going to be taking Biology.

Here’s the list of the core classes in middle school and high school:

English

This year is very stressful because it’s the year that counts the most; colleges look mostly at the grades from this year.

Everyone is freaking out and taking AP and SAT and ACT prep classes. A shit-show in its purest form.

Grade 12

- English

Read books like Othello, The Crucible, and The Scarlett Letter

Senior paper

- Math

Calculus

YIIIIIIIIKKKKKEEEEESS

College course

- Science

AP Biology, Chemistry, or Earth Science 

Students must choose one or the other or an elective science like Marine Biology or Anatomy

- Social Studies

Government and Economics

Two courses that are each only a semester long. You either take one class for the first semester and switch to the other class second semester or switch the classes every other day

- Foreign Language

Nobody even cares anymore

This year is the most fun year of high school; although some colleges do still look at the grades, many students are already committed to college and get a case of “Senioritis” which is when they let their grades slip and take it easy because they don’t have to worry about impressing colleges.

OKAY THAT TOOK A LOT MORE TIME THAN IT SHOULD’VE

2. Know the Types of Classes

Depending on their skill level in the area, kids can take a variety of different versions of these core classes. There’s reagents classes, honors classes, and advanced placement (AP) classes.

At least in New York, reagents classes take state-made reagents at the end of the year as a final exam.

Honors classes are basically advanced versions of reagents classes. They teach at a faster pace and go more in-depth into the topics. They, too, take reagents at the end of the year.

AP classes are the hardest of them all. They’re college-level classes and make students eligible to take the AP test. Depending on what score they get on the AP (1-5), they can skip the 101 classes in college.

(Example: If a girl gets a 4 on the Global History AP, she can skip Global History 101 in college)

Junior year is also the year students take the SAT and ACT, huge tests that are very important for college.

Other schools may have other kinds of classes like IB, but this whole list is JUST ACCORDING TO MY EXPERIENCES.

3. Just Know that School Is Not the Worst Place on Earth

Although there are certain times when school can be the absolute worst thing ever and there are a lot of flaws in the education system, it’s not all downsides!

School is a place where you learn new things, meet new friends, and get to hang out with people you wouldn’t hang out with otherwise.

There are extracurricular activities available for FREE that you can join, and aside from being academic, school sponsors a very nice social climate that is crucial for kids to develop skills in communication and interaction with others.

Of course, high school is also the place where people start getting into serious relationships, which you can research here.

I really hope this helped!
