Recommendation for Options Textbook?

[Dax]

We're soon going to be starting our Math Options topic which is Calculus, our teacher is going to be using his own college/support material and has asked us students to get a proper textbook on options topic.

are there any recommendation for any textbook which is good for this options topic?
also, are there any good math workbooks of sorts that we could use for Math HL

[don't you wish]

We're using the Oxford textbook for calculus, which is excellent for explanations, but not for excercises. I'd suggest that your IB coordinator signs you up for http://app.ibmaths.com, which has some really excellent excercises. It does cost your coordinator a bit of money, but I'd say that it's worth it.
