But that's not the case. Timely revisions help reiterate important information in one's mind. This will ensure maximum retention of key pointers that will contribute to achieving the desired results.
  • Not practising enough mock tests and sample papers - Practice makes a man perfect!! Students should not neglect the importance of practising questions. Subjects such as physics and mathematics require a lot of practice and with too many formulas and calculations involved. Therefore it is advised to practice various types of numerical questions. For this, candidates can take the help of JEE Mains sample papers and mock tests. The JEE Main 2025 mock test and sample papers are based on the syllabus and paper pattern only.

What are the common mistakes you should avoid in JEE Main 2025 exam?

There are many reasons why a candidate makes mistakes while preparing for the examination. It is essential to know the reasons to ensure that they avoid making common mistakes in JEE Main 2025 exam.

  • Not solving questions completely - Many times, while preparing for the exam, students prefer to just understand the concept to solve questions rather than solve them. This lazy involvement creates unnecessary confusion while solving the JEE Main question paper. It becomes a major drawback to solving other questions as well. Not having enough practice with the JEE Mains questions will result in losing makes on easy questions.

  • Wasting time- Another common mistake students make while attempting the questions in the exam is to jump from one question to another without solving the already-read one. This leads to wasting a lot of time. Skipping one question just because the other one looks easy is not advisable. It leads to missing out on both the questions and a waste of time. There is no doubt in saying that time management is the key to scoring high.

  • Unable to read questions properly - Authorities generally ask questions having keywords such as which of the following is TRUE, or which of the following is NOT TRUE. Students do not read the question properly and ultimately attempt the questions incorrectly. It is essential to read the questions carefully and then attempt them.

  • Doing experiments during the examination - The question paper of the exam contains three types of questions - known, not known but needs to be solved, and completely unknown. Always attempt the known pattern questions first and then move forward to the unknown but need to be solved. Remember if you have prepared well then the difficult question is difficult for all. Do not do experiments by solving completely unknown questions. While solving the JEE Main paper, picking up the right questions is important.

  • Not practicing much - Practice makes a man perfect!! Students should not neglect the importance of practicing questions. Subjects such as Physics and mathematics require a lot of practice and require too much calculation, therefore, practice all the numerical value questions.

Hello Mahitha,

At an 88.57 percentile in JEE Main, a CRL rank of 168000 and an EWS Category rank of 24000, the likelihood of receiving CSE or other top branches in NITs/IIITs through CSAB counseling are almost negligible, especially for general/open category seats. That said, as a female EWS candidate, you may have a few chances in:

  • Lower ranked NITs/IIITs (NIT Mizoram, NIT Nagaland, IIIT Una, IIIT Bhagalpur, etc.)
  • Non-core branches (Civil, Metallurgy, or Biotechnology)
  • Home state quota, if applicable and available at CSAB

Hello Aspirant,

With an All India Rank (AIR) of 145214 and OBC-NCL rank of 48284 with Uttarakhand domicile you have chances of getting admission in College of Technology Pantnagar (COT Pantnagar) through UTU counselling. However this will depend on cut-off trends, seat availability and your branch of choice.

Note that COT Pantnagar fills B.Tech seats through UKSEE/UTU counselling and based on JEE Main scores. Being a Uttarakhand domicile and OBC-NCL category should help you with state quota reservations. If you wish to improve your chances:

  1. Apply through UTU counselling.
  2. Look for branches that have relatively low cut-offs.
  3. Keep under similar colleges in UTU also as backups.


Hello Aspirant,

In JEE Main, questions are mostly conceptual and test your understanding, application, and problem-solving skills in Physics, Chemistry, and Mathematics.

1.Multiple Choice Questions

2.Numeric Based questions

  • Questions are based on Class 11 & 12 syllabus

  • Mix of easy, moderate, and difficult levels

  • There is also negative marking so you should be aware before answer that questions.

All the best for your examination.
