i don't recommend the calculus text book, professor Jan's (<3<3!) slides are very thorough and it's all available online after the lecture. if anything they're actually slightly better than the textbook because it provides step by step stuff.
linear algebra perhaps, because Dr. Harvey doesn't provide full slides and she writes on the slides as she lectures. i didn't really use mine, i'm a robot note taker and jot everything down.
highly recommend both econ textbooks simply because it helps with revision and most of the material taught are in there. i used mine a lot anyway, can't say much for others.
edit: student guide and workbook is *****, dont bother.
