Struggling with Study Habits in High School

This is a very specific issue I have been having so I dunno if anyone will be able to help but lets try. I am a senior in high school and am taking two ap classes (literature and calculus) and am learning that my study habits suck, or anytime I try to study I just don’t know how to. I need to work on this desperately before I go into a STEM major in a stem specific college, but I am struggling. Visuals work great for me, and I’m trying to use different colors in my notes to help my brain organize what I am doing as I do it (it’s been helping a ton!) but I need to make review sheets for a lot of things—the funny thing is I am bad with details in math. This is funny because I am amazing at details in english and other things, just not when solving equations. I need to pass with higher than a D in my math class to get college credit for concurrent enrollment and I’ve been trying to review the entirety of all of calculus 1 and what we’ve learned in calc 2 thus far but it is full of details and half the time I try to review by writing down the main points but I either get bored or realize I really should prioritize another thing of homework and then I’m too tired to do review sheets. Any advice? Maybe I could find review sheets online to print out and thoroughly look over and make flow diagrams for? I need more to try as a neurodivergent person, and though I’ll be using computers for math work in engineering in my future I just have to get the fundamentals down now! I already decided I will start learning how to calculate math equations with programming now so I can have a new skill and review some math but theres a bit of a programming learning curve right now (Though I am learning Python for a class rn). Sorry if this is a bit messy of a paragraph I was coming up with ideas and thoughts as I types whoops.
