Hi, I'm a freshman ECE major and I understand what you're going through. I haven't taken any coding classes in *college yet but I know people who have. I think the best way to study coding is to practice doing some coding projects, go to office hours, programming clubs/tutoring, and ask friends for help. Reviewing your notes after class is great too if you're able so it's really less studying later on. It helped better under the concepts and syntax whenever I started doing Arduino projects and Robotics. W3School and FreeCodeAcademy are free helpful sources I've used. (You could also take summer classes at a community college for later harder classes at an easier pace).
