How to score 70 to 80 % in BSc?

What I think is, scoring 70 to 80% or above in BSc is not rocket science. I don't know why I don't score so much. All you have to do is to follow the below techniques:

• Go through your syllabus completely.

• Only make notes of those topics that are part of your syllabus. As per my experience, most universities don’t ask questions in the BSc exam that are out of your syllabus. So prepare your syllabus carefully.

• After you’ve completed the syllabus go for previous year question papers. You can get these previous year papers either from your professors or from nearby book stores.

• In these lockdowns we will try to arrange previous year question papers for you.
