Greetings all,
I have read a couple of reviews of Chad's videos here on sdn, but I still have a few questions. I was wondering if these videos really teach you how to do the math problems in a highly quick and efficient way. I remember VIHSADAS had made a post on how he was able to get a really hight PS score based on how efficiently he was in doing the mathematics involved in the exam. Does Chad help in understanding concepts and developing intuition? I remember VIHSADAS had wrote
Does Chad's video's help you develop these skills? Also does chad have have biology videos. Sorry for the long post and any advice would be greatly appreciated.

On my real exam, I used no more than ¼ a single-sided page for scratch work on the PS. Because I was intensely comfortable with order of magnitude estimation, decimal estimation, log estimation, dimensional analysis and conceptual knowledge I could eliminate answer without too much written math. Sure, you could use the formulas to explicitly solve each problem, but using estimation along with formula manipulation will save you whole minutes on the real exam.
