Is this an unreasonable amount of summer work?

I’ve never taken an AP class before, and am taking AP World this year. I only decided my classes for good on July 15th. Our summer work is 200 pages of notetakin, and notes on four hours worth of videos. We have a test on all of it the first day back. That seems like quite a bit of content for us to learn only from the textbook. We don’t have any guides on what the test may be on other than “the summer work.”

Is this unreasonable?
