It depends on what science.
In all sciences, it’s good if you can make your own study group as it’s much less boring when studying with friends. Study for moderate amounts of time and take a short break after each study period.
Biology: Biology is difficult because it requires a lot of memorization and retaining to be effective. There are several ways to improve your memory, including eating healthy and color coding your notes.
Chemistry: Work out some past chemistry problems from quizzes and tests as it is likely that your final incorporates elements from them. This is true for just about every class you take, unless your professor is a complete butthole.
Physics: Arguably the hardest but most rewarding when you understand. I too have trouble with understanding how to do physics problems and my grade is suffering because it’s a completely new subject to me. My best advice would be to deeply analyze every problem you’re given. This is especially true for engineering physics. What I mean by deeply analyzing is to see what forces are being applied, what elements from the current and past chapter are in the topic, and what equations or formulas to use.
I hope this helps. Best of luck!
