hi I am in 12 standard cbse what can i do to get good collage
It's really a thoughtful one now. And concentrate on 10+2 exam then on jee, any state board exam you're interested. Learn all basics, solve as many problems as you can. Practice.
All the best.

Either it is physics , chemistry and maths or
Physics, chemistry and Biology or may be some other courses such as arts , or commerce.
