These notes legit helped me graduate (Econ degree). Was so close to getting flunked but the streamlined layout really helped me tunnel into key concepts. Had to contact customer service a few times for questions but they were always on the ball. 10/10 if you need that extra boost in class. I sure did.

OneClass is the best resource to find quality notes and practice problems. I found the notes there are well-organized, clear, and useful. I love checking midterm/final review notes on OneClass because it's really helpful.

This service is such a fantastic idea. I signed up and right away was able to start getting study notes for my classes. I would recommend anyone to sign up, its worth it! OneClass has helped me pass my courses, I am not sure I could have done it without them. Just make sure you cancel your subscription over the summer.
