mind mapping!

the other day, Rab mentioned mind mapping in class.
In high school, i found a book called Mind mapping by Tony Buzan, and it proved to be very beneficial in constructing notes and summaries. To use such devices in class just goes to show how in touch Rab is. its going to be hard to be better than Rab! |X
i think there is a translation in Japanese too, and its fun to read.
if you know of any other useful methods to cope with studies, please tell me!
