You can basically choose from science, arts, commerce for +2 or go for a diploma.
Know your interests first.
Know that if you are determined and dedicated to whatever you choose, you will be rewarded. Choose what you are passionate about or at least what you will enjoy doing.

You could choose for any course that provides computer education, like CS bifocal course or IT in Science or go for a Diploma in CS. You may then choose to go for a BCA.

Well, I think the best way would be to go for computer science bifocal course along with PCM (of course Science). Appear for state-CET or JEE and take admission in a good engineering college that provides CSE or IT.
