Straighterline Math courses - what are they like?

[acamp]

I took Calculus II.  That class was both extremely difficult and somewhat doable at the same time.  Everything except the final is open book.  So, the ability to search was very helpful.  The final is not open book, but one page of notes is allowed.  I recommend spending a lot of time on developing a final exam note strategy.

Thanks for the response.  Since the other tests (minus the final) were open book, was it easy to score 100 on all those?  Or even with it being open-book was it still difficult?  And are the tests all multiple choice?
