Yeah, usually l look up specific youtube videos on certain material or chapters...but most of the time you have to purchase the books from my school as the professors don't give too many alternative books to buy. And with the Pandemic, you can only buy New...how crazy is that! Because the "used" books can't be bought because of other people's fingerprints on it or risk of spreading the virus. Hopefully that will change in the future, but right now you can only buy new and it all comes wrapped in layers of plastic.
l completely understand the safety precautions for used books but having the Only option to buy new is really crazy....especially at $200 a book!
