Gaps in math knowledge

CS student here, interested in math. Had Calc II this semester, and I'm required to take Calc III, Differential Equations, and Matrix Algebra still.

I never really liked my math classes and saw them as kind of a burden, when I had calc I during online classes I cheated on everything and only really remembered overarching concepts such as derivatives & limits. I actually had to retake calc I because I never did any homework in there and got a D the first time.

This semester I had Calc II in person, which everyone finds hard at my university because it's like leftovers from calc I and the units aren't connected to each other very well. I studied and actually did really well, Calc II went over integration techniques, series and sequences, applications of integrals, parametric equations, and polar coordinates. I was studying with people and teaching them to do things that tend to be more confusing such as Taylor series and trig substitution, and it's given me a lot of motivation to actually try.

Now I want to fill gaps in my knowledge. I don't have a math class next semester, it's an easy semester, so I want to spend the semester filling all the gaps in my knowledge and learning Calc III/DE content so that when I get to those classes, I'll already know the content and can easily get an A.

What's the best way to go about identifying and filling gaps in my knowledge? It seems like everyone teaches calculus in a different order too, things that are part of Calc I at other universities are part of Calc II at my university (volumes of revolution for example), and vice-versa.

I really dislike reading textbooks, I'm super ADHD and whenever I read a textbook, generally I get bored within one page no matter what it is. I had a really shitty teacher this semester for Calc II, literally couldn't understand what he was saying because he was from eastern europe or something. I usually learned by looking up youtube tutorials for stuff in class.
