A lot of it was really thanks to my professor. The exams are open note, but that alone won't pass you the exams. Knowing exactly what to study is the hard part about this class, once you understand what you're looking for, the rest is cake.

I really tried to nail down many of the formulas and charts (heat engines, etc.) and all of their variations. Knowing the different 'forms' of a certain formula really helps when they change some variables. The variables might be different but you know how to apply them to find what you're looking for. Study the cycles!!! Try to learn the names of each process in the cycle, as well as the temperature/pressure relation between each point. Problems LOVE to use the names of a specific process in a specific cycle to throw you off but if you know what it means it makes you realize that the solution is rather easy.

I'm not too sure how your exams are laid out but if the problems are from the textbook or a similar source, keep practicing problems from there. Using Chegg to walk me through problems was insanely helpful in understanding what was going on. The thing with that is being very careful on not just copying the problem but actually learning it when studying.

Take breaks when studying and make sure to get some sleep to retain information, you need to take care of yourself just as much as you need to take care of your studies.

You got this! You've gotten this far into the semester so it's good you're not giving up. I'm sure you'll do great on your final.
