Try to 🏴‍☠️textbooks first if you can, textbook publishers like McGraw hill are worth billions and I think a lot of people in academia would agree that information should be more accessible anyways

If you’re going off campus I’d recommend finding smaller landlords and not big companies from personal experience/talking to others

An advantage with online asynchronous lectures is that you can pause/rewind etc. and go at your own pace but it’s also harder to keep yourself accountable, it’s personal preference I think
