Top 5 Tips to Crack JEE Main 2021
Starting early:
Maths is one of the tough subjects among the three and requires a lot of hard work and time. So, starting early is the best solution as it will not create any panic at the last moment. Last moment pressure is harmful to one’s mind as the person could do things wrongly in spite of knowing the correct answer or can do the calculations wrongly resulting in negative marking in exam.
Make a schedule:
You need to practise regularly to increase your speed and accuracy and for that planning is the first step to achieve any goal. Make a list of topics you need to do in a day and at the end of the day mark it done. To make the study process more efficient you can check your performance through online test series which are based on the exam pattern. There are 15-18 tests papers for JEE Mains and 9-10 tests papers of JEE Advance, after giving tests you will get your performance report which will help you find your area of improvements and your speed. To score good marks one should do JEE Main mock test daily for a month so he/she can improve his mistakes and also increase his speed to do calculations.
JEE Main Weightage for maths topics:
Algebra:
Emphasize on algebra as it is the highest scoring topic. It consists of various sub-topics such as
Probability.
Quadratic Equations and Expressions.
In this topic, you need to remember the formulas thoroughly. Algebra is the most fascinating topic and one can score good marks easily understanding the basic concepts. The questions are easy to solve and can be done in a short time if you have done good practise.
Minimal amount of questions are asked in the JEE exam from this section. To clear this section basic concepts are needed to be cleared and this section comes in many competitive exams so it should not be ignored. You need to remember the formulas thoroughly to clear this section and to remember them you can make a list of formulas topic wise so it would be easier when you revise.
Analytical Geometry:
It is the method of analysing shapes. You need to practise a lot of questions based on curves, lines to score good marks. It is the maximum scoring topic, you just need to learn the formulas well and apply them carefully. Some major topics under this section are:
Straight lines
Circle
Ellipse
Parabola
Hyperbola
Calculus:
Calculus is considered as the most important part of the Mathematics section for JEE Mains. It is divided into two parts:
Definite Calculus
Functions
Limit
Application Derivative
Continuity
Differentiability
Integral Calculus
Differential equations
Definite Integration
Indefinite Integration
Area under curves
Before starting integral calculus your concepts of definite calculus should be cleared it would be easier and faster to understand. It covers around 35% of the total question in the exam. Be up-to-date with the formulas and method of working in calculus.
Vectors & Miscellaneous:
This section has the least weightage but full marks can be scored by remembering only the formulas. The questions asked from this section are not complex and very easy to solve in less time.
Tips for preparation:
Previous Years’ Papers:
The most important suggestion would be to analyse the JEE Main question papers for Maths thoroughly. This will give you an idea of the topics you need to focus on and the ones that you can leave or briefly go through.
Learn Theory First:
The most important recommendation for cracking the JEE Main 2020 Mathematics Exam is to first learn the theory well from study materials and then revise it regularly. Since you have very limited time and have Physics and Chemistry to study as well, you can first study from NCERT XI and XII textbooks and then solve the previous year questions.

Thank you !
Hello,
Your daughter's JEE Main percentile scores of 70.203 (Session 1) and 50 (Session 2) may correspond to an approximate rank range of 1,00,000 to 2,00,000. Given this, she might have a chance in branches like Civil or Electrical Engineering, but admission to Computer Science Engineering could be challenging due to higher competition.
Regarding fees, CIT Ranchi's annual tuition fee for B.Tech programs is approximately INR 1,00,000 to INR 1,20,000. Additional expenses for hostel and other facilities may bring the total annual cost to around INR 1,50,000 to INR 1,80,000.
Hope it helps !
Hello,
Based on previous year cutoffs for JEE Main in the EWS category, a rank of 10 lakh in JEE Main and a category rank of 117,126 would likely make it difficult for you to secure admission to a government college in a popular branch like Computer Science or Electrical Engineering.
In the past, the cutoff for EWS category in top NITs, IITs, or other good government colleges has been much lower (usually below 50,000 for top branches). For your rank, the chances of getting into good government colleges with core branches are slim.
However, you could still have a chance in some of the newer or less competitive NITs, IIITs, or government colleges, especially if you are willing to opt for branches with lower demand.

Hello,
Based on your JEE Main score of 52 and category rank of 58,842 (in Tamil Nadu), it might be difficult for you to secure admission in NIT Trichy, IIIT, or IIITDM Kancheepuram, based on previous year cut-off trends.
NIT Trichy (National Institute of Technology Trichy) : The cut-off for general category students is usually very high, and even for reserved categories, it remains competitive. Your rank is likely to be far from the required cut-off in most branches.
IIITDM Kancheepuram : Similar to NITs, IIITDM also has a high cut-off, but it may vary slightly. Your rank may be challenging for some of the top branches, though you might have a slim chance in some lower-demand branches.
IIITs : The cut-offs in IIITs also tend to be quite high. With your current rank, securing admission into the top branches might be tough, but again, there could be a chance for some lesser-demand branches.
In short, based on the previous year's trends, getting admission into these institutes with the given rank might be challenging, but you could explore other options or consider waiting for spot rounds or other counselling options.
Hope it helps !
Hello,
Yes, you can avail the EWS (Economically Weaker Section) quota during JEE Main 2025 counselling , provided you have a valid EWS certificate issued on or after April 1, 2025. This certificate must meet the criteria set by the National Testing Agency (NTA) .
You can participate in counselling through JoSAA, CSAB, or state-level counselling, depending on your eligibility. Ensure that your EWS certificate is valid and meets the required criteria to avail the benefits of the EWS quota.
