Any tips on how I can learn to understand a subject instead

I'm going to start my first year of college soon and I'm trying to prep myself in advance. I've looked at some instagram reels explaining what I can do to study and what-not and one of them is the Feynman Technique. I've tried doing for chemistry and physics while I write notes but it never really clicked for me as I feel exhausted after a bit. I am still open at giving it a shot though since it very well could be me not doing it right.
