Hello Sakshi,

From my opinion board marks does not matter if your goals was something great. So I suggest some career guidance you should choose.

1. You didn’t study for exams but you have the potential to do something in future - Try to get some IT college (computer science) private / govt. and study hard there (If you are pcm student). You could join various engineering college and take any branch of your interest ( CS/IT , Chemical, Biotech , Civil , Mechanical etc .).
2. If you don’t want to study and have your own passion or hobbies like sports , photography , music , dance , acting , art etc . Go for it dude , Marks can not decide your career or destiny . You could become successful in any field if you are ready to give your hundred percent for it (not 50 % ) .
3. If you are biology student , you also have a lot of options in private section and medical .

All the best!!!!
