I took accelerated with Jenkins, and the class moves very very fast. He expects you to learn new formulas / concepts quickly, and expects you to know how to apply them to problems immediately. I'd advise attending win blocks, especially if you moved up a level (or stayed the same). He's accessible able outside of class, but win blocks usually fill up fast as many students have questions. He's homework heavy, and quiz/test heavy. If you can learn new math concepts quickly, you'll be fine.
As with many things, don't procrastinate on the essays. Also there's a good chance that he won't seriously check all your notes on the books, so don't stress out too much on those. The essays are also graded somewhat harshly compared to the other assignments. Also, if he does word stems, those are basically free points, let them pull up your grade even if you don't like doing them.
