Sir, I failed in MATHS in Class 12 board exams 2019. Now, Ive registered myself as a failure candidate to reappear in all subjects in 2020. So my question is, will i have to give practicals and submit projects of all subjects like previous year?

Piyeta Ghosh 2nd Dec, 2019

Hello aspirant

Now that you have registered yourself to appear for all the subjects , which means you are repeating 12th standard again. The board views you as a normal 12th grade student.

Hence, you have to appear for all the exams (internals and externals), practicals, assignments etc.

Hence, the answer is YES.



If a medical student with 70% in cbse class 12th board can be able to apply BITSAT form 2020?

Malini S N 2nd Dec, 2019


Candidates must have passed their class 12 with Physics, Chemistry and Mathematics as compulsory subjects and candidate who have opted for biology must have 75% aggregate score in Physics, Chemistry and Mathematics.So,if you have physics,chemistry and maths as compulsory subjects,then you will be eligible.Candidates must also score 60% individually in Physics, Chemistry and Mathematics.

All the best!!


last year I will give practical exam of all subjects and pass in all subjects but fail in theory so this time I also give practical exam ?

Devraj choudhary Student Expert 23rd Nov, 2019


Yes, you need to appear for each and every exam this time irrespective of whether you passed last year or not. Your new result will consist of new grades or marks replacing the older ones.

can I fill improvement exam after 1 year gap . I was unable to fill form this year

Ayshi Ghosh Student Expert 28th Oct, 2019
I'm sorry but a dropper after class 12 th can not appear for improvement exam. You can only appear for improvement exam in the year after you have passed your boards. However, do not worry in most sectors marks do not play a major role nowdays. All the best!
