Dear aspirant, I wonder why you worry for 11th score after you passed. It is the 12th score which matters everywhere. Just try to focus and study. You will surely do wonders. You might be finding it difficult because either you might have created a self doubt or you may not be studying the correct way or possibly your teacher may not be good. Good luck.

Hello Nisar Ahmad, I can understand your angst and the anxiety. The best way is for your son to choose the branch he desires. I am sure you, as a person, would have realised that education is just a stepping stone. There are plenty of more things that matter for successful career. Presently mechatronics is the in thing. But aeronautical engineering branch too had great potential for future. Best wishes to you.

When you take admission in a university, the board through which you cleared your 10+2 does not matter. The difference between the two boards is in the difficulty level. If you choose CBSE, the difficulty level is much lesser than that of ICSE. So choose the board on the basis of the pressure you are willing to take.

To pursue BBA it is good to take the commerce stream from CBSE.
