Hello,

If this question was about Arts or Commerce stream then you could definitely do that. Since you are a student of Science stream, it is going to be good thing for you. In class 11th you will have to deal with basic problems and in 12th you will have to solve advanced level questions, do you think that if your basics are not cleared, you will be able to solve the advanced level problems.

You shouldn't skip even a single section from your syllabus specially from Mathematics and Physics. You must be good at these two Subjects if you're willing to pursue Medical or Engineering course. And if you're basics are not cleared then how will you manage to solve Questions of Engineering background.

Good Luck.
