Ofcourse.It is totally up to you.

You can go for any stream and courses.

There are so many options after 12th Science.

BSc ,B.A., BTech (must have maths in 12th),MBBS (must have Biology in 12th),BCom etc.

Ask yourself what you like in the course and what you don't like in science.

The decision you make today will not just affect your tomorrow but will determine your future.- Keith Craft

Feel free to ask if you have any more queries.

All the best!
