the benefit of the course is that it's a regimented, fully planned sequence of study. further, you can get additional practice with the question types that you need extra help with jut by going online. The best thing about the course is the CAT practice. I took 4 CAT's before taking the GRE. practice is the best thing to prepare you i think. however, the course also clearly communicated very good strategies for all the question types, and if i had questions, there was an instructor to answer them.
basically, i think the course is pretty optimal prep for the GRE. first time i took the GRE i studied almost every night using books for about 5 weeks. i did well. next time I took a 5 week kaplan course. i went up 150 points. the books did not communicate the material (to me anyways) as well as the course.
part of the course may be very elementary and and boaring (the parts that you're naturally best at). but i found that the time I spent working at it made that material more automatic. for example, i started out as great at sentence completion. when i learned the strategies i answered the questions faster and had a way to quickly check my work.

p.s. i think that memorizing vocab IS important, but it is way behind other things. like cara says, you need to first learn the strategies. a few examples that i can remember: learn the common analogy bridges. there are not that many different ones(as of now). learn how to approach antonyms using highly concrete definitions and considering alternate meanings. Do multiple word sentence completion by plugginig in the simplest word first and then go back and chek the others. Learn the types of reading comprehension passages, types of questions, and learn how to break down a passage into topic, scope, and jist etc... you can probably find all this in a book but i think it's better articulated in the course.
p.p.s: the books sometimes say "this book is all you need to study for the GRE." they lie.
