Congrats on finishing your first semester! College can certainly be an adjustment in terms of the amount of studying that you are expected to do. The first thing I would recommend is to stay on top of your daily readings. If you actually read the chapters before class, you will get the most out of the lecture. That way, you don't have to cram to study 10+ chapters at once. The next advice I would give is to find a place to study that is comfortable for you. A lot of what you take in and remember has to do with your environment. If studying in your dorm room has too many distractions, or the library is stressful, I suggest going to a coffee shop or a different quiet area of your school! Lastly, It's important to find the right time of the day to study. Some people work better in the morning than at night, so you can build your class schedule around that. Some things that work best for me are physically writing my notes down instead of typing- I find typing to be too mindless and I would have study guides over 50 pages long with unimportant information! When I would hand write my notes to study, it was more deliberate and I would know whether or not I understood something.
Hope this helps!
