Hi Arnav

It is totally your choice weather to apply for 2subjects or all subjects. The marksheet of improvement exams is also different from your original marksheet. incase if you get less marks in improvement exams than best of two will be considered. So their will be no problem in skipping 3subjects. But on your improved marksheet only the marks of two subjects will be shown and others will marked as absent.

Hope this helps !

Hi Arnav!! Hope you are doing well!! Improvement exams are conducted by CBSE to give the students a chance to improve their marks in which they want. It's totally fine if you apply for 5 subjects in improvement and only go for 2 subjects. It won't affect any of your present score, the papers whose improvement exam you didn't give, their initial scores will be considered for your evaluation(the score which you got in your normal boards paper) and other papers for which you sat for improvement exam's, their new marks will be considered. So, overall, there is no problem if you don't want to sit for some papers.
