If you are not good in maths and science subject, then please don't follow engineering, as it is really tough.
however, don't worry, the world is full of successful people from different streams of study, and not only engineering, so talk to your parents and choose something that you are comfortable with
if you have interest and skill to follow something you like, with necessary skills, you will put more efforts, that will result in dedication and finally success.....if you choose otherwise, then there is a possibility that you might struggle in grades, finally affecting your career for the whole life.

BBA - is about management, generally followed by MBA - maths is not important.
SCIENCE - is about applied and pure science (applied = engineering, pure = theoretical). While you need to be good in science and maths for pure science (B.Sc), you need to be really excellent in them for engineering (B.E. / B.Tech)
