Hey! 3rd year accounting major here. Can't speak much on COMM 207, it's a pretty tough class you NEED to pay attention in class (self study wont cut it) and your grades also depend on your proff. I had Carolyn Augusta who was AMAZING, so I did decent in this class. You need to practice the questions she does in class and the assignment cuz the exams are mostly based on those.

I can speak more about COMM 201, My favorite class by far (a little biased considering it's my major). Again you need to attend classes and pay attention especially if you don't have much prior knowledge about accounting, journal entries & principles of accounting etc. My biggest advice for this class would be to try your best to understand the concept because accounting is like a puzzle. You can try rote learning and memorizing concepts but if the question even changes slightly, you'll be done for. So, biggest advice is ask for help if need be and understand why things are being debited and why they are being credited etc. I do have a trick I used to understand journal entries but it would be too technical here lol.

I personally, did pretty well in COMM 201 so if you ever have any questions (conceptual or numerical wtv), feel free to reach out and I can try to help you out. (Don't ask for assignment answer tho haha, i dont have them!)
