Warming up with GMAT RC

Finally, after warming up a little bit (and staying away for different types of insect texts ;) I was able to score a tiny bit more then 82% of correct answers on my next block of Reading Comprehension texts.

So now it looks like it'd be the easiest part of manage, with some practice and just keeping up my English vocabulary.

I've already passed three types of questions (according to the first book of GMAT Review). They are Problem Solving (PS), Data Sufficiency (DS) and and Reading Comprehension (RC). To prioritize them, I'd write something like this:

RC < PS = DS

PS and DS are almost equal in hardness (for me), while RC is fairly easy one. Bear with me, and I'll compare more categories to those two.
