I'm really struggling at doing well on the aforementioned categories in the math section. The rest of the stuff is fairly straightforward, but I can't understand how to do these categories once it gets to even medium level questions. I've tried looking at the stickies here, but I still can't do the practice problems (again, anything past the easy examples are too tough for me) and I've also tried using the Manhattan guides, but I'm not getting any better (the RTD chart I found was more helpful than the strategy discussed here). Does anyone have any suggestions on what to do? This is really worrying me, so any help would be great!
I have discussed a work rate strategy here:http://www.veritasprep.com/blog/2011/03 ... -problems/
See if it works for you.
Also, I have discussed lots of combinatorics concepts in my blog starting with this post: http://www.veritasprep.com/blog/2011/10 ... inatorics/
(many subsequent posts are on combinatorics)
After a couple of posts, they get a little tricky.
