can I repeat 12 or repeat the board exams.whenever I got lower marks for grouping?

Dear candidate

If you fail, then you can write supplementary for the subjects that you have failed and in the case of lower marks you can write betterment which is conducted only once after the main examination but you cannot repeat how many times you want which means you cannot repeat board examination whenever you want and there's another option which is that you will have to cancel all the exams and attempt again which means study 12th again for scoring more marks for grouping with this an year will be wasted and you need to study your 12th class all over againand  write all your board examinations again so, i recommend you to not choose this option ao, you better get good marks in your main board examination if not try to gain them in the betterment examination.

All the best

Hope this Information is helpful
