15 min study and 10 min break or 25 min study and 15 min break
If you adhere to that for the day than set up a reward policy. If you fail, do a punishment; however, make sure the punishment will hurt you in a decent way, so you don't take it lightly.
Why do you need to study? Ask this first and foremost. Everything else is bullshit if you don't ask and understand this question.
Study with friends WHO CARE about their grades. Make friends with people who are smarter than you, consistently get better grades and overall are just better than you, sounds stupid but it really works.
There are online apps to help you with this. Also look at study tactics. I know this works because I used to get C's and D's in high school and I am now a mostly A student with honors and deans llst. However, the american school system is garbage, so grades don't reflect much.
