GMAT Strategy

Hi.. I took the GMAT about 10 days ago and got a rude surprise : 690..
Was expecting at least a 710, and was thinking more along the lines of a 730 to 740.

The story is like this:

Had been generally going over GMAT stuff from end Jan without a real date in mind. Just casual practice without any schedule or plan. Started getting serious end Feb, which is when I finally booked a date for 2nd week of April giving me exactly 1.5 months. By then I had finished 50% of OG.

In the remaining time I completed OG and Kaplan. I also took the GMATPrep, and Kaplan Tests every weekend(more or less). Apart from an initial Kaplan shocker(570) I scored between 710 and 730 consistently on most tests.

Thereafter I did all the PS, DS & SC problems again from OG. Thought I was quite strong in CR & RC and didnt go over them again(mistake ??).

Skip to 1 week before GMAT(1st week March):
Right in the beginning of Feb I had taken the 1st test from GMATPrep(710) and had not touched it since. Thought I would give it another go, since I have a poor memory in any case, and don't really remember answers. To make it more realistic I also did the AWA section(for the first time.. more practice required??).. got a score of 760. Knew this was partly because I was familiar with some of the questions, but was quite satisfied with my preparation overall.

Spent the remaining week just going over OG stuff and strategies mentioned in Kaplan.

Skip to Test :
AWA went off all right
Quant went off fine as well. Just managed to finish in time. Had to rush through the last few questions.
By this time I was feeling quite confident about the exam. Took all the breaks provided.

Verbal - started off OK, but soon hit a crazy science-biology RC passage, and things started going downhill from that point. Everything started looking the same and I appeared to be guessing most of the time rather than actually choosing an answer because it was definitely the right choice...
started running late, and most of the questions towards the end were blind guesses..

Final scores :
Quant : 49
Verbal : 34
Overall : 690

AWA just came in : 5

Needless to say, I was very disappointed, as this score left me neither here nor there.. close, but not nearly good enough..

I have booked another date for the second week of June.

Now for those who have been patient enough to read so far let me sum it up:

Material used : OG & Kaplan
Tests : GMATPrep & and the Kaplan (one which comes on the CD with the book)

Target Score : 720+

Now I think, given enough systematic preparation I could hit a 750, but I have a full time job which keeps me rather busy, and am really aiming for around a 720 which I think should be enough.

I have around 45 days now, in which I really need to get my act together.
I think I mainly lost concentration on the day of the exam, and on any other day would have done better, but it also tells me that my Verbal preparation was not good enough, since I got bogged down so easily.

I would really welcome some advice on how I should go about preparing for my 2nd attempt. Needless to say, its very difficult getting my self to start studying again.. I would also like my preparation to be solid this time, and not leave things to chance.. I dont think I could go through the agony of a 3rd attempt. If need be, I could re-schedule it and give my self more time, but the next attempt has to be it. Meanwhile have bought Kaplan 800.

Thanks for reading through this rant and looking forward to some feedback..
