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.

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!!
