Hi,
I've been lurking around this forum for quite some time, and I just wanted to say thanks for all your help! I took my GMAT yesterday and got 690 (90%) with Q 43 (70%) V 41 (93%)

. I'm excited about the score even though I know that it is not an especially high score in comparison to many others at this forum. Anyway, I think I could have gotten 30-40 points higher with a couple of months extra, but in my case I don't have the time so I'll settle with 690. I think a 41 on verbal is ok given that English is my second language.
I always enjoyed reading these GMAT debriefs so here goes:
Material used:
OG 11th
OG Quant
OG Verbal
Manhattan Review Guides (all except RC and word problems)
GMAT Club Challenges
CATs taken:
Powerprep 1 560 Q38 V28
Powerprep 2 570 Q34 V32
MGMAT 1 720 Q45 V42 (this was after going through the
MGMAT books)
GMAT Prep 1 700 Q44 V41
GMAT Prep 2 690 Q44 V39
PS:
This was my biggest challenge. Even though I'm still in school, I haven't seen most of the GMAT stuff since early high school and it took some time to bring it back. I guess my best advice is just to go back to basics and make sure that you know all of the concepts 100% before moving on. I seriously started off first just doing simple calculations in order to get the feel into my fingertips.
DS:
I found this somewhat easier than PS even though the format itself was puzzling in the beginning. I think that it is easier to make educated guesses on DS than PS, but that's just my personal opinion.
RC + CR:
I didn't focus much on these parts of the test as these were my strengths from the beginning. Just be careful to note excactly what the question is asking for on RC (e.g. "according to the passage" means explicitly stated in the passage an so on). Also, on RC I only read through the passage without taking notes, I tried to take notes a couple of times but I feel that it takes too much time and just distract me.
SC
Get the Manhattan SC book! It is recommended all the time on this forum and it deserves to be.
Strategy:
1. Do 50 % of OG: This was mostly to get used to the format and to build my skills gradualy. Most of these questions is too easy to be representative anyway (except some of SCs).
2. Get Manhattan guides for all weak areas: I really recommend this series. In my case, it made all the difference! It pushed me from having ~ 580 to ~ 670. Go through each in detail and do the corresponding problems in OG for each subject area.
3. Finish last 50% of OG: Went through the remaining questions in OG and OG quant using a timer and a
error log.
4. Do CATS: I think you should at least have done 3-4 cats before going for the real thing. It gave me more confidence; I just tried to imagine that it was just another trial CAT

5. GMAT club challenges: These are essential if you are going to do well in quant. I didn't have time to go through more than three of them, but I'm sure that if I would I could have broken the 700 barrier. Most of the questions were on a too high level for my quant skills though, but I learnt many smart tricks that I could use on easier problems.
Ok, I think that was it.
I got one question I hope some of you can help me out with: Does anybody know how GMAT verbal scores correlate with TOEFL scores? I need 100 on the internet based one and I just want to get an idea of how much studying I have to do (frankly, I'm not especially motivated to do any studying at all right now

)
Cheers
