Yes, I remember using "Cell" in my 10th grade AP bio class. I can say that it contained a LOT more information than any AP bio book, or any college bio book we had used later (Lewis' Genes VII is pretty thick, though, too). And the information was far more interesting. It was there that I read about the "perinuclear cisterna" and other fun stuff - which I won't see again until med school.
It's a great book, but to really retain ANYTHING, you would have to go over it in a year, or maybe half a year minimum. If you try the whole winterbreak thing, you will forget it.
I tried doing that two summers ago - I went through Boyce/DiPrima's Differenial Equations and Boundary Value Problems, and did ALL of the questions. However, since I did it so fast, I forgot all of it, and now don't know how to solve 1st and 2nd order ODE. I would have to open the book again to figure out. Really pathetic.
Right now, I am actually doing some quantum mechanics self study and TAKING IT SLOW. I started about a week ago, and am only on page 45 or so (out of 670). This is because I am making every effort to understand every single mathematical derivation, and every single physical and philosophical point, and I am taking the time to do every problem. Consequently, I know more from the 1st 45 pages of this book about QM, than I did from an entire whorlwind course, where I just learned to do meaningless manipulations and calculations.
