I've taken four SL courses. You don't need IC at all. For most of the SL courses, just get the e-book, make sure it works to search for specific terms (no OCR versions, no physical text), and use it during the non-proctored exams. Repeat the 1st exam until you get close to 100%. I would suggest reading the other SL threads for tips on getting through SL efficiently. No need to reinvent the wheel when there is a very efficient way to pass most SL classes quickly. Note: There are a few SL classes where the above won't work.
