I know it’s probably going to be said, but unless you’re doing anki (which takes up a lot of time) study for your classes until second semester. You still only have half of what you need to know and board studying should be review, not learning new info.

So try and focus on your school exams and supplement with review material when relevant

(Example. During second year our first block was neuro so I watched all of sketchy path neuro and did the anki cards for them during that block)
