<p>Glad to have helped. At Ross, there is an hour of lecture each day and 3 days a week there is a 1 hour seminar. The lectures generally either explain new concepts, explore interesting tangents, or will go over old problem sets. The seminars are run by different people and some of them explore more tangential stuff like set theory while others focus on discussions of problems from the problem sets. Another important thing to note is that you work at your own pace. Oftentimes, a lecture will go over a proof from an old problem set so if you’re going at a fast pace you’ll have proved it by yourself but if you’re going slower they’ll give you the proof sometimes.</p>
