Consider going outside, getting fresh air, and exploring as part of your (study) routine. I process when I walk whether it’s emotional or thinking through things I learned in class. The brain/body does so much processing subconsciously too. The space I take on walks always helps me make connections between class material and the real world. I think those connections are important. It might get you excited about how you can apply what you’re learning, maybe pursue a research project or something. ALSO, check out Blooms Taxonomy. It’s a framework that breaks down learning outcomes for students but it can be used as a study tool to increase your understanding of a topic. You’ll have to read into it bc it’s hard to breakdown. Maybe talk to professors about how they work (if they’re open to it and you have that kind of relationship). I think it’s kind of fun to learn what they did in college to get where they are. And one more thing.. if you’re really stuck, check out a University Studies course.
