Good textbook, although the module now has Unit 11 as optional, so I didn't do that one. I might go back and read through it later, but I enjoyed the section on sequences - and complex numbers aren't as daunting as they first seem either.
I've enjoyed the module overall - and I'm definitely someone who learns better from physical books than online alternatives. If it was up to me, I'd have more exercises in the books themselves, but if you're doing the module, you have the unit quizzes on the module website to help practice. And I do have some other maths textbooks that cover these topics so I can get extra practice that way too.
