I started my GMAT Preparation 3 weeks back. From the begining I knew Verbal Section will be a big challenge (as english is not my native language therefore less confidence and less skills). I am putting a lot of effort in the verbal section but still i am not able to increase my verbal score and this part is really very very frustrating. My target GMAT score is 700+ but i am not able to get it solely because of the verbal section.

Following are Test Scores (in chronological order)
Diagnostic Test OG: (PS: Above Avg(17); DS: Above Avg(18) ; SC: Above Avg(13); RC: Avg(9); CR: Avg(8))
GMAT Prep Test 1: 550 (Q - 44 and V - 21)
Diagnostic Test Kaplan: 600 (Q - 45 and V - 28)
Kaplan Test 1: 540 (Q - 37 and V - 23)
Power Prep Test 1: 560 (Q - 47 and V -21)

Details of PowerPrep Verbal Sections (Last Test):
SC --> 5 out of 16 wrong
CR --> 7 out of 11 wrong
RC --> 8 out of 14 wrong - 4 Passage (2-Medium with 3 Que Each and 2-Long with 4 Que Each)

Just 3-4 days Before PowerPrep Test 1 found these docs
Spidey Sentence Correction Notes
Rajat_nda SC notes
Sahil's Grammar Notes
GMAT Flashcards --> Eric's
Manhattan SC

Also these r the books i hav:
OG 11
OG -Verbal Rev
Princeton Rev
Kaplan -2008
Kaplan 800

(I have gone through OG 11, Princeton and Kaplan 2008)

Week Sections: RC(Big Time) then CR then SC.

PS and DS - Not a problem (i can improve)

I have a lot of ground to cover in Verbal and that too within one month. I feel if i can get atleast 38 in Verbal i will cross the 700 mark.

Can anyone pls suggest what i should do to improve verbal section (especially in RC and CR).
