I used eyeQ for about 3month everyday...
I believe it helped somehow...
BTW, I scored +3 on my second time...
you know... RC is the only section that you can't improve by studying for certain amount of time...
And I had no other RC study material except for practice tests...
So, I just bought it & they came to our school gave us special discount...
If you are interested in getting one, please PM...
I didn't really study for RC too much--all I did was go through the Topscore reading tests. I used an abbreviated version of the kaplan mapping strategy. Just put a few keywords down for each paragraph so that you know what part of the passage you have to go to to find the answer.
