I did something similar for walks and replaced the evening commute back with cycling on Zwift. I finish work then jump on the bike in my office, and it allows me to break up the work day and the start of my evening. It's been very effective for my health over the past two years.

Look into spaced repetition, and more specifically Anki. It would seem it's the ideal tool for the problem that you're facing : studying for exams, not for the long term.
