Indeed, you can get affirmation in the science stream after the twelfth grade. You will have to rehash class eleventh and twelfth for doing such.

You will be fresher in the science field because the idea and essentials are inverses. Still, you will be qualified to seek science. You will realize that science is fairly more earnestly than commerce and for your situation, you should be enough committed to these as from the trade field.

Make a mentality, set up an arrangement, and stick to it.

Good luck
