Tumblr media
Gate 2024 is almost here and our young aspirants have never been so restless. Our students are ready and we can feel the excitement and anticipation for the exam building up. However, every passing day brings us closer to the BIG DAY, the day of examination. And for that, VedPrep Chem Academy has curated the perfect guide for all the GATE aspirants out there. Curated with Ved Sir, this guide will solve all your queries regarding “How to prepare for GATE 2024”.
So let’s dive right into this ultimate guide!
A Quick Summary
GATE or Graduate Aptitude Test in Engineering is an examination for aspirants who aspire to pursue Master of Engineering, M.Tech., and Ph.D. GATE lets aspirants get direct admissions into the most prestigious universities of our country such as IITs, IIITs, and IISERs.
Moreover, the top GATE Rankers can get direct or interviewed jobs in PSUs like Indian Oil, GAIL, and CIL.

GATE 2024 Pattern of Question Paper (Latest)
Since GATE is a highly competitive examination, your rank is what matters the most. No matter what your GATE scorecard says, it’s your rank that will decide your future. Therefore, preparation for a good rank starts with understanding the examination first. This is the first step of our guide “How to prepare for GATE 2024”. We’ll be analysing the GATE examination for Chemistry. However, the strategy for GATE 2024 will be applicable for all subjects. So, let’s go through the exam pattern!
The exam will have a total of 65 questions.
10 Aptitude based questions
55 subject based questions
There will be 3 types of questions in the GATE 2024 Question Paper
Multiple Choice Questions (MCQs) carrying 1-2 marks each in all papers and sections.
Multiple Select Questions (MSQs) carrying 1-2 marks each.
Numerical Answer Type Questions (NATs) carrying 1-2 marks each in most papers and sections.

Trend Analysis of GATE (2021 – 2023)
Before a future strategy for GATE 2024, let’s take a look at the GATE question trends throughout the years. We’ll be going through the trends for all three sections (Physical, Organic, and Inorganic chemistry for better understanding.
Question-wise Trends GATE Physical Chemistry
Tumblr media
After analysing the trend in Physical chemistry for GATE, we can conclude a few things:
Physical Chemistry had a whooping 30 marks weightage from 2021 – 2023. This fact should be more than enough for anyone to start focusing on Physical Chemistry even more.
Physical Chemistry has been consistently delivering around 20 questions every year. With over 40% weightage, physical chemistry becomes 
Topics like Quantum Chemistry, Chemical Kinetics, Physical Spectroscopy, Thermodynamics and thermochemistry, and electrochemistry are very important. As these are the topics from which questions are being asked consistently in the GATE examination.
However, if we look at the marks weightage trend, we can clearly notice that there are more essential topics. Topics like  Quantum Chemistry, Chemical Kinetics, Physical Spectroscopy, Thermodynamics & thermochemistry, electrochemistry Solutions, and solid state become highly significant in this case.
Strategy to crack GATE 2024
Now that we’ve understood the pattern GATE has been following throughout the years, we can finally use our analysis to curate the ultimate strategy so that you don’t have to search for “How to prepare for GATE 2024” anymore.
