CBSE 10th

477.5 is not a bad score you can still have chances to convert into a good B school with a good GDPI e performance.

No, the board from which you studied does not matter if you are aiming for a foreign study and actually passed the board with Good percentile. Colleges always prefer high-rankers rather than a particular board students. Hence, the State, CBSE or ICSE board is irrelevant while applying for colleges abroad.

There is a very high chance to get IIM -B at 99 percentile but you should have to work very hard for it. You should also focus on your profile building as it's very important for getting a call from top IIMs.

Hi,
It really doesn't matter now. As you are graduated now which is no doubt but a very good and energetic thing. And yes of course you can go for LLB. It is possible now, only if you are going to work harder.

Hi,
You have a decent profile in terms of your past academic records. So, I would suggest you score as much as possible, rather in short prepare well. As you are from a non-engineer background, you have a good chance of getting a call from IIM-A in 98 percentile. So, prepare well and ace the top IIMs. Best wishes!
