hi,
this is my first post. My Gmat date is 22 Sep that means i am left with precisely 40 days. i have taken two test both the test( one Kaplan+ 01 Pearson) i got 560. My target is 700+ like most of us. I got 44 in Quant and 22 in Verbal. i have Manhattan books and lot of other stuff also with me. I have done Manhattan once but my SC is just not improving. I have some basic questions.

1. How can i improve my verbal, specially SC.what should be my strategy. How many question a day,which book..etc etc.

2.My CR is pretty OK as per OG stand..however i want to know that how can i get more tougher questions than OG. and is it required. Coz i have only 40 days that means at the max i have 120 hrs to improve some 200 marks???

3.Quant i have started with manhattan will be switching over to OG 10/11/12. Any other books fast to improve Quant.

4.one more question how much marks difference it will come if i go from 40 to 49 in quant in terms of total score marks ..any guess ( assuming m
y verbal remains the same that is 23 or so).
