Multivariable Trouble! Help Please!

Hi all!
I am currently taking Multivariable Calculus from my school’s online program and I am struggling to understand all of the concepts from the way my textbook describes it. I have had success in the past with other math courses by reading books that make these concepts very easily accessible such as the “Calculus I for Dummies” or even the Princeton Review books for other AP classes. This gives me a basic overview of the topics and then I can understand my textbook and the problems better. Is there any such supplemental reading that I can get for Multivariable? Please let me know! Thank you!!!

Engineer here…it took me a while before it all "clicked’ when I took this class.

Also get a tutor if necessary
