Does anyone have a site good for online textbook guides / notes?

I'm using America Past and Present, the Revised 6th Edition (6th Edition notes would be fine) for my APUSH class. Could anyone help me find an online guide with this textbook?



I don't understand why textbooks have to be so difficult. It jumps from 1644 to 1678 back to 1601 to 1622... It's so confusing! If you know why they do THAT, it would help. Or if you know a way to better undestand the book even though it does that?



Thanks so much!Does anyone have a site good for online textbook guides / notes?
Speak to your AP teacher. The " skipping" is probably due to the book taking a topical approach rather than a chronological one./
