You can go with courses like polytechnic in computer science or go with some private diploma courses in computer science like National Institutes of Information Technologies, etc. However, you can not go to formal computer science degree like Bachelor's in computers, etc.
Hope this helps. Thank you.
well a biology student can not take B.TECH CSE course.you need to pursue maths,,physics and chemistry in your 10+2 .well you can pursue BCA(bachelor of computer application) where students who have studied biology as their subject can also take.
