I just finished my GMAT Sentence Correction part and (sadly) should say that this is still one of the hardest piece to be done and, I guess, the least coachable one as well. I had the highest deviation of my correct percentage rates for the questions from this section.
Here comes the final difficulty equation for the GMAT sections:
CR < RC < PS = DS < SC
Okay, so I'll take a day or so for AWA theory practice and will start working on different techniques of "cracking the GMAT".
