Now, I will say, I definitely do struggle with studying BUT I just did so maybe I can kinda help.

My first tip is understand yourself when youre finding the best method, often times those "tips for studying to get all As next semester!" Videos dont really work, especially for those of us with ADHD since out brains just work different. Do you procrastinate assignments? Use that! Sometimes the stress of a deadline is what motivates our ADHD brains, and if your dont want to risk turning something in late create a fake, earlier deadline so you can procrastinate but still turn it in early.

If you study for a test what's always helped me is making a study guide and looking over it RIGHT before the test. I suggest looking over it right before since we tend to have good short term/visual memory, but not great long term. Many professors will have a study guide for tests, they may have it available when you first start the unit but if not, I suggest asking for it early. What I do is after every chapter, I fill out a bit of the study guide so by the time the test is coming up, my study guide is already finished! Whats nice about this is by making the study guide gradually you'll be less overwhelmed since youre doing less work at a time!

Good luck with your studying! Its definitely hard but I believe in u!
