Hello Rishi,You are writing for B.Tech exam for many years.My sincere advice is follow your heart ,what you want to be in a life instead of listening of peeers ,find out your soul voice first ,than try to discover path towards that goal.

Be motivated and hopeful towards life circumstances and move forward ,not mingle at any situation.Try to calm over every situation in your life.

As per careers option you have too many option which you can opt as you are a science student.

hope this helps you .ALL THE BEST
