Hi KWLee,

I know you are doing economics, a subject which has lots of quantitative analysis and hence studying mathematical proofs and derivations are inevitable.

Can you suggest me how to activate a maths text? During activation of mathematical textbook, I find that trying to dip in 20% to get 80% of the meaning does not work. Because the words are so technical and explanations are quite precise as well. It's quite hard to skip any 'crap'.

Also, I have to slow down to comprehend the proof, which is something i don't want to happen. Otherwise, I would not have learnt PR to increase my studying speed. Also, how did you mindmap these technical stuffs.

I know I'm quite demanding but you are a successful PRer in activating highly technical materials and. Would you please share your experience with me? Thanks.
