JEE Main 2026 is expected to be held in two sessions. NTA holds the entrance exam in two sessions to provide the following benefits: 

  • Candidates will get two opportunities to improve their scores in the exam if they are not able to give their best in the first attempt. 
  • In the first attempt, the candidates will get a first-hand experience of taking an examination and will know their mistakes which can be improve while attempting the test for the second time. This will reduce the chances of dropping a year and the candidates would not have to waste an entire year.
  • If anyone misses the examination due to reasons beyond control (such as the board examination or health issues), then candidate can appear for the second session. 
  • A candidate is not required to take both the sessions, however, if someone appears in both the sessions, then their best NTA scores will be considered for merit list preparation.

JEE Main 2026 Chemistry Preparation Tips And Tricks

Before attempting the papers, one must be knowing shortcuts and roadmaps to understand the concepts as well as formulas that are very important. If you do not have any shortcuts, create your own and use them frequently to get into the habit. Also, make sure you have a list of JEE Main important formulas that are handy and readily available to revise.

1. While attempting numerical problems, try to round off the data given or being used, so that you can easily calculate and arrive at an approximate solution that will be closer to any option provided in the questions.

2. If you do not get the correct answer of a numerical problem in first attempt, then try to calculate the entire sum. Make sure you practice this technique.

3. Related to the real life problems based on concepts, it will be much easier to analyze any given problem.

4. Revision Is A Must-Revise as much as possible and try to make a timetable to fit the JEE Main High scoring chapters or topics.

5. Anticipate the mistakes you often make and practice enough to get them corrected before the exam.

6. Make a list of JEE Main important books and chapters that you are comfortable with and keep them highlighted or note the most scoring topics in your very near access.

i gave my 12th boards in 2025 feb, in which i got a compartment in result. i had an option to reappear in all subjects, I'll be reappearing in 12th boards 26, so how many jee adv attempts do i have and will there be any issues in registration of mains and advance as i will pass my12th in may 2026?

Hello

Since you’re reappearing for your Class 12 boards in 2026, that will be counted as your official passing year. So, you will be eligible to write JEE Advanced in 2026 and 2027. Although you submitted the boards in 2025, that attempt won’t be considered due to the compartment. JEE Advanced rules allow 2 attempts in 2 consecutive years after passing 12th. So you still have both chances left, which is great! Just make sure you meet the other eligibility conditions too. Keep your focus strong, you’ve got this!

Preparing books for learning JEE main

Hello aspirant,

Start with NCERT in every subject for JEE Main.  For physics, use H.C. Verma and D.C. Pandey; for chemistry, use R.C. Mukherjee and O.P. Tandon; and for mathematics, use R.D. Sharma or Cengage.  J.D. Lee assists with inorganic chemistry, while Morrison & Boyd assists with organic chemistry.  Practice chapter-by-chapter Arihant or MTG past year's papers.  For efficient preparation, concentrate on clear concepts, frequent revision, and passing practice exams.

Thank you

Is income certificate required during registration of jee mains of current year??

Hello,

Generally an income certificate isn't required for the JEE Main registration, but if you want to claim the EWS quota, then you need this. You must provide the certificate, issued by a government authority, as proof of your family's income being below the specified limit for the reservation category you wish to apply under.

I hope it will clear your query!!
