Great idea Clark, but AlexK is right. Learn the system, on some non-pressure material. You'll actually get to your goal faster (as he echo the words of the forum).
Use August or even the last half of August for refresher. Do about 3 chapters from each text a day. When you get to the end of the book, do it again. Well that's the layering idea of PR.
Now, here's some advice to a older persson. You are dead on, with the idea of completely mastering the material in the early years. However, I will add to your plan. DO problems. This will help immensely. As for calculus. Try adding a book of tables to your PR list. List of derivatives and integrals.
The other thing I would do, even if you never feel comfortable with activation and you will if you stick to it, is to PR the chapters before they are covered in the class. Then let the lectures be your activators. I'll tell you the this as a FACT, for myself and anyone you has done it, if you read the material before class you will learn it much much much better than if you read it after the lecture. It's the same amount of time, but the effect is incredibly different.
Old fart signing out.
