From 2026, JEE Main will not allow calculators in the exam. This means students will have to do all the calculations by hand, either mentally or on paper. Both physical and virtual (on-screen) calculators are banned.

This rule will affect both speed and accuracy. Without a calculator, students may take more time to solve long numerical questions or problems that need many steps. Mistakes in addition, subtraction, multiplication, or division may happen more often if one is not used to manual work. But at the same time, regular practice can make students faster and more confident with numbers. Manual calculation also improves understanding of formulas and concepts.

For speed, students who depend on calculators may find it harder to complete all questions in time. They will need to practice mental math, quick simplification, and use of tricks like estimation and remembering standard values such as squares, cubes, and trigonometric ratios. Over time, this practice can make them nearly as fast as before, but it needs effort.

For accuracy, students must be careful while doing rough work. One small calculation mistake can give the wrong final answer. So it is better to stay calm and double-check important steps. Accuracy is more important than rushing through.

Overall, the ban on calculators will make JEE Main more about logic, manual accuracy, and time management. Since this rule is for everyone, it will not make the exam unfair. The students who practice manual calculations more will have an advantage.

Hello

Don’t worry, it’s not a serious mistake.
You just selected the wrong option for your qualifying exam type.
If you studied under CBSE or any State Board, you can fix it easily.
When the JEE correction window opens, choose your correct board name.
Even if it stays the same, your marksheet will clear any confusion later.
So stay calm it won’t affect your admit card or eligibility.

Hello,

If a student has failed in one board subject (like Maths 1A), they can still appear for JEE Main Session 1, as eligibility is not verified at the time of exam.

However:

The JEE Main result will be displayed normally with percentile and score.

The student will not be eligible for admission or counselling unless they pass all subjects in the board exam before the admission process starts.

So yes, they can write and get results but must clear the failed subject to be eligible for admission.

Hope you understand.

Hi,

If your school board has given you a roll number then enter that number in the JEE form and if the board hasn't issued the number you can leave the registration number column blank.

Hello,

If you mistakenly choose the CBSE-I instead of the CBSE in the JEE Main form, don't worry. You can still correct it during the NTA correction window. Then you can just log in to your JEE Main application, edit the board names to CBSE, and save the changes.

I hope it will clear your query!!

Hello,

You do not need to fill the registration number column because it is not needed. You can fill your 12th class roll number on the 12th grade roll number column and that will be used to submit your application. Ensure you fill all the necessary information correctly.

Hello

Yes, you can fill the JEE Main form even if your father’s name is different on the Aadhaar and 10th marksheet.
Use the name exactly as it appears on your 10th marksheet, since that’s considered official for exams.
Aadhaar is mainly used for identity verification, so a small mismatch won’t cause issues.
Keep the Aadhaar update slip or request number as proof that the correction is in process.
If NTA opens a correction window later, you can update the details then.
Make sure spellings are accurate and consistent across all other details.
