I have got 2nd division in bihar board result so what can i do
Sorry to hear that. I would say depending on your aspirations you have to take the next steps. Now you didn't mentioned the 10 th or 12th board. If you are in 10th, then you can get admitted in 10+2 with Arts/Commerce. You may not get science with 2nd division marks but it may vary.
If you have passed 10+2 with the provided percentage then you can go for Bachelors courses and pursue your dream out of it.
Now this is a very broad topic and you haven't provided sufficient information based on which I can answer you more informatively.
So I would recommend you to get back to career360.com (//career360.com) with proper question specifics so that we can provide you the info you needed.
I hope this might help. Good eve!
