Yamini, if NITs are your goal, with all due respect from 38 percentile to be able to score atleast 97 percentile, what you should not be doing is rely on easy topics. You need to work double harder than you have already put in. You need to focus on the topics that carry more weightage over the others. That way you have a chance to score more. Our JEE Knockout package can help you in your preparation: https://learn.careers360.com/knockout-jee-main-april/ . Alternatively, the topics that you need to focus to score more are:

In Physics, Modern Physics take the top slot with 5 questions. Heat and Thermodynamics, Optics, Current Electricity, Elcetrostatics get 3 questions each. Magentics has 2 questions and the rest get 1 question each.

In Chemistry, Transition Elements and Coordination Chemistry, Periodic Table and Representative elements take 3 questions slot. Thermodynamics and Gaseous state, Atomic structiire, Chemical Bomding, Chemical and Iconic Equilibrium, Solid State and Surface Chemistry and Nuckear Chemistry and Environment get 2 questions slot eacch and the remaining get 1 question each.

In Mathematics, Co-ordinate Geometry gets 5 questions. Limits, Continuity and Differentiability, Integral Calculus get 3 questions slot each. The rest get 2 and 1 questions slot.

Hii Rahul!
The topic equilibrium is divided into two parts, Chemical equilibrium and Ionic equilibrium. Mainly, questions are asked from Chemical equilibrium. You must prepare topics such as Arrhenius laws, association, dissociation, and numericals from each topic. Solve previous year question papers. That will give you the idea of questions asked.
Hope this helps.
Good luck!

The topics important in Structural Organisation in Animals are :

Types of tissues

Body structure of different animals like : Earthworm , Frog , Cockroach

Hope this helps you.

CAT is an online examination of 3 hours duration.The questions in the exam will be of MCQ and TITA type totaling 100 questions. MCQ are multiple choice questions, for which candidates get multiple answer choices. Each Question has 3 marks and a wrong answer takes away 1 mark. However Type in the Answer questions are exempted from Negative Marking.

CAT exam paper can be Categorised into 3 parts:

Quantitative Ability
Verbal Ability and Reading Comprehension
Data Interpretation and Logical Reasoning

The Verbal Ability section and Reading Comprehension has 34 Questions, Data interpretation-Logical Reasoning section has 32 MCQ questions and Quantitative Ability has 34 MCQ questions totalling up to 100 questions. Each Question has 3 marks and a wrong answer takes away 1 mark.

First things first, know the syllabus. And go through the previous papers to analyse and prepare a comprehensive plan and set priorities according to the importance of different topics across sections.Customise your own study plan based on your strengths and weaknesses. Gauge your preparation from time to time by taking mock tests. Solve questions to check your levels of preparation but not to set any targets. Remember, its ok to have cheat days and relax. But make sure you have a plan and stick to it for the next few months because even Rome wasnt built in a day.


NCERT books will sharpen your basics and you need strong basics for preparing for any entrance examination. Once your basics are in place, because the time period for preparation is quite less, your preparation should be extensive and thorough.

Quantitative Aptitude covers almost 30% of the CAT question paper. QA can be categorised into Arithmetic, Algebra, Geometry and Advanced Mathematics. Practise chapter by chapter and develop mental calculations. Like practise more of basic summation, subtraction, fractions and tables. Numbers, Percentage, Profit and Loss, Simple and Compound Interest, Ratio, Proportionality, Time-Distance, Time-Work, Mixtures, Averages, Partnership, Permutation and Combinations, Probability, Set Theory, Progression and Series, Line, Angles, Triangles, Quadrilaterals, Polygon, Circles, Ares, Volume, Height and Distance, Coordinate Geometry, Basic Trigonometry are few important topics.

Preparation tips:

Because this section involves mathematics and takes most of your time, your focus should be on solving the problems efficiently in the beginning. Even if it takes time, practise upto perfection. Practise as many questions as you can in the conventional way. As and when you get a grip on the subject, you can go for short cuts. Memorise tables, square roots, cube roots, conversion from percent to fraction, etc. Solve sample papers on Mathematics. In the beginning, do not worry about the time it takes. As you practise, you will get the hang of the subject and it will be easier for you.


In Verbal Ability session, command on your English, Grammar, Vocabulary, Understanding of the given paragraph are of more importance. Reading English NewsPaper will also help you in your preparation.

Preparation tips:

Read articles from time to time. Follow newspapers, magazines, and watch the news channels and browse the internet to keep yourself updated. You will need a lot of reading to help you in the comprehension section. You will need speed to help you in this section and you can achieve that only by thorough practise and reading. Take time to understand the question because most answers are interlinked.


Data Interpretation and Logical Reasoning needs to be practised as much as possible. Comparison of data, Data Analysis, taking clues, interpreting missing data, coming to conclusions and making future projections will be covered under this Category. The questions here are interlinked and so if you get one formula correct, cracking the next few questions will be easy. So it's important to memorise and practise formulae. You should cover topics like Data tables, Data Charts, Bar Diagrams, Pie Charts, Graphs, Data Comparison and Analysis.

Preparation tips:

As this is the most tricky section, this needs a lot of practise. Solve as many sample papers as possible to get the hang of the section. Make notes when required. Regular practise can help you understand and solve the questions easily as time goes on.

Overall,once you know the syllabus, it's easier from there on.Go through the previous papers to analyse and prepare a comprehensive plan and set priorities according to the importance of different topics across sections. Customise your own study plan based on your strengths and weaknesses. Gauge your preparation from time to time by taking mock tests. Solve questions to check your levels of preparation but not to set any targets. Remember, its ok to have cheat days and relax. But make sure you have a plan and stick to it for the next few months
