Every morning I review my Anki cards, and speak the answers aloud (So I know I'm retrieving the information and not simply recognizing the card). Every afternoon I watch prerecorded lectures at 2x speed and create cards based on slides and what the lecturer emphasizes. As far as the "bigger picture" is concerned I make a few cards asking myself to summarize some general concepts. The key is making sure you get it right when you make the card, or following up days later if the card makes no sense.
My grades and quality of life shot up by a good 10-15 points on my last two exams doing this.
There is a lot of information you need to retain over a long period of time, while simultaneously learning new information. Its not really a learn and purge, hob-nob with the professor to show you're smart kind of deal. Anki spaces out those reviews and re-exposes you to the material, briefly, days or weeks later to keep it fresh.
What you're asked to do in undergrad may be very different from medical school, bare in mind. The goal for the first 2 years is to answer stuff about this on a standardized test we will take in 2 years time. So how we do it may not be (yet) relevant to you.
