i also have a bit of a problem with studying because i procrastinate a lot and i find it hard to focus sometimes, so ive researched a lot of studying methods. i haven't tried all of them but you can try and see if anything works for you!!
- explaining the topic(s) you need to learn to a child, a sibling, other family member or just like a plushie or the wall > apparently this should be really helpful because it forces you to make up your own explanation to explain the topic and it forces you to actually understand because you have to explain it to the other person/thing understandably
- doodling while studying > this works in a way that you are supposed to get like a paper and a pen/pencil/anything else and while you are studying, you should be doodling with your other hand. nothing specific, you can literally just scribble and draw circles, absolutely anything, but the point of it is apparently that it's apparently supposed to help you focus better on the stuff you are trying to learn
- listening to music while studying > this doesn't help everyone and it might distract you instead, but ive heard that apparently for some people, it's really helpful when they listen to game soundtracks during studying!! ive seen people say they listen to doom soundtrack or night in the woods soundtrack, but i think it can be any game that you might enjoy, and the logic behind it should be that the game soundtracks are designed and made to help you focus on the game while you play / also apparently white noise helps some people
and then i guess i just have some smaller tricks that have helped me sometimes (when i have the motivation) > asking your friends/family members to quiz you, revising after every class or at least reading the topic once or twice every day/every second day/with some other regularity (of course this is for like longer preparatory studying, not when you have to study for a test that's next day) and reading it out loud or writing it down - the writing down method had helped me a few times, it's like making a cheat sheet so i try to shorten the sentences so that i don't have to write too much, but still go through everything, and essentially this helps me memorise it a bit better !!
im not sure if any of these will help but i hope that at least something might be helpful and good luck !!
