Hello dear student,

It's totally depends upon you what is your goal to become in life. And what do you see yourself in next few years as in where you exactly want to work. Options are unlimited but you have to make your mind. You can go for IIT JEE because you have maths in your class 12th this is entrance exam that you give if you want to become an engineer and you want to do BE or BTech from any government engineering College or from IIT. Then if you choose biology side you have several option you can give Neet and become a doctor. Or you can try for BSC with any of the above subject and do a specialisation after that you can pursue masters. So as I said options are many but you have to clear your mind what you exactly want to become

There is NDA ,AFCAT government exams to become government official. Etc

I hope the above information is helpful

Thank you
