Where is a good place to get notes on textbook chapters?

I have an AP US History quiz coming up (open note), and we use the third edition of The Enduring Vision textbook. If you know a good place online to get chapter summaries, please let me know!Where is a good place to get notes on textbook chapters?
Here is an advice for you. Doesn't matter if it's an open book test, you need to study hard for it. Students really make a mistake by taking open book test lightly. They spend half time looking for answers during the test.

Study hard. Read the chapters thoroughly and understand them. Don't just read it, try to understand the concepts.

You will be better off this way. when the test will come, you will probably know 90% of the answers and that will give you enough time to look for few hard questions. You would also get to know where the topics are and during test you can just find it quickly.Where is a good place to get notes on textbook chapters?
