Hi guys
i really need help

Genuine thoughts and not false hopes:)
I have gmat scheduled on June 2nd. I have been preparing hard since last 3 months.
My scoring pattern:
GMATPrep 1: 700
Kaplan CAT 1: 600
Princeton Review CAT1: 700
(Q48 V37)GMATPrep 2: 710
Kaplan CAT 2: 680
Princeton Review CAT2: 720
(Q51 V37)Manhatten CAT 1: 690
(Q47 V37) (I didn't consider this valid as i had to pause the clock to complete the Quant section)GMAT Prep 1 (Repeat): 720
Princeton Review CAT3: 730
(Q50 V41)Kaplan Test 3: 620
(Q50 V31)(This drove me crazy) Analysis told me that though some questions were tough, but I did avoidable fundamental mistakes in othersManhattan CAT 2: 720
(Q49 V39)(Again had to pause the clock for both quant and verbal. For Quant i stopped the clock like forever:), For verbal I took 10 mins extra).I started with a target of 750 (which i think i have already lost), but i cant afford a score lesser than 730.
Few things i need to know:
- Are PR tests easier than acual GMAT?
- I found
MGMAT Q section absolutely tough. I was left with 10 questions when the time elapsed. Verbal was easier than quant, but i still fell around 10 minutes short. Is
MGMAT an tougher by an order of magnitude than actual gmat? If that is so, I wonder what is the use of taking difficult mock, when one knows that this is no reflection of how one would do on acual gmat. I have the same question with kaplan, though i did not find kaplan as insanly difficult as
MGMAT. People who have reported scores close to 700 on
MGMAT, were you able to complete the sections (Q and V) in 75 mins each. To me quant was like an open time test

- OR should i get my date postponed (which I hate to think of) and strive to get a 700+ within stipulated time on KAPTEST and
MGMAT?
