The staff at FlightSafety will give you a pretty complete set of training manuals and study guides. If you are taking an initial course, the classroom portion of the training is 5 days, and the simulator portion will be another 4 to 5 days.
It should be a pleasant course - there is enough content to keep you busy, but not so much that you are overworked. Just listen to the instructor during the class presentations, then read the same subjects in the training manual later than evening to review.
The classroom presentations are designed to follow the manual very closely, so you should not need to take very many notes at all. In fact, if you have more than a single page of notes at the end of the one week course, you're doing something wrong, because everything you need is written down in the training manual and the study guides.
