Hello Experts,
I took the GMAT 45 days ago and scored a 690 (Q 42 V 42) with a horrendous IR and AWA score ( IR:4 AWA:4). Immediately after I saw my scores on the screen I decided that I had to re-take the test. Exactly two weeks are left for my final tryst with GMAT. In these two months I maintained an
error log and meticulously noted down my short comings. I registered for the Empower Gmat course and went through their modules. I did notice an improvement in my D.S abilities but then came the shocker when I took a GMAT Prep CAT ( 3rd attempt). I anticipated repeat questions and got 5-6 repeats in every section (didn't remember the answer to any). But since a familiarity with the question, even when you don't know it's answer, gives you an edge, I expected 730+. I scored a dismal 690 (Q 48 V 37)

.
I also took two Manhattan CATs after that (my second attempt). Scored a devastating 630 (Q39

V37) on the 1st CAT and 640 ( Q42 V35) on the 2nd CAT. Now, i'm totally devastated by these abysmally low scores. But I've made it a point that I won't let the "scores" affect my mood and general well being. I'm just doing questions from Gmat club forums and taking Manhattan CATs (4 left) to practice pacing. There's only so much I can do in two weeks.
I have three questions:
1. Will I profit from going through all the O.G problems once again? (Although I know most of them verbatim). What other sources should I refer to?
2. Do I have a chance of scoring a 730+ in two weeks.
3. What other things should I do to ensure that I don't fail miserably on D-day?
I'd really appreciate if an Expert helps me.
Thanks,
Joshua
