Nick, you're right about the revision schedule at different intervals. What I was trying to say was that students must revise, otherwise all their efforts that they invested in studying will be wasted.

I currently use a multitude of varied reading/ memory systems, depending on the material. It's all a matter of individual perference. You've to do a lot of experimentation and see which one is more or less suitable for certain subjects. From my experience, I like using Howard Berg's Mega Speed Reading for leisure. On the other hand, I would rather use the Reading Genius for academic pursuits. I use Mind Maps for everything.
