Sir, my brother's percentage in 12th 2018 is 55 and his interest is in CSE. How can he get a good college?

There are various options for him to get into an engineering college like state engineering entrance examinations UPSEE, WBJEE etc. He should also try to get into a private college too. Good luck.

My friend, You should tell him to do BCA. It is the best course for CS and IT. You can find list of colleges providing the BCA courses in India. Go for the Shiksha official website, and find the college of your choice. Just go to Shiksha and search colleges by courses.
