I took the course which met four times a week. I regularly gave myself 2 hours to prepare for each lecture. I would read the chapter and attempt the problems at the end of the chapter. In class we would go over the chapter together, do the In class Compendium passages and discuss them, etc. After class hw would vary from 2-7 hours since every chapter had different amounts of passages and free standing questions.
This thread contains the HW syllabus which is important since problems in the big white books are not sectioned by chapter. If this is not current to your books then you may need to find someone to scan theirs for you. . .

hopefully it matches up to your books.
I really valued my class time since I gained insight from my classmates. It helped me improve comprehension of passages and I could ask questions (even if I couldn't see the board since my PR classroom was a ridiculous shape). I also used every minute of office hours and managed to get additional office hours after several instructor absences and the ridiculously crowded, poorly designed classroom gave me ammunition against the center director (can it really be called a classroom if you are 2 feet away from the wall, short leg, on one end of the room trying to read the board 30 feet away, hypoteneuse, making your viewing angle almost parallel to the board???).
Be sure to find help with topics that seem to defeat you!!! And stay on schedule!
