Best Book to prepare over summer?

[Roy c]

Next semester I will be taking Calculus 2 and Multi-variable calculus together and was wondering what textbooks would help me prepare and allow me to become comfortable with the material that will be covered. I have not found a thread that discussed a textbook(s) that would prepare for both, so forgive me if there is one.

There’s a couple of resources online:
Khan Academy
Www.mathispower4u.com

And bookwise:
Openstax University Calculus
Keislers Calculus book

Both are god and both are free to download.
