Need advice regarding GMAT preparation(currently in chaos).

First of all thanks for sharing your journal, but i must admit that you are on much better ground at this time than I am, with regards to prep. The one month window is all i got and in this time one thing is sure that i cannot join any prep course such as knewton etc. The only sources available to me right now are the Manhattan series ,GmatClub forum, OG(books) and about 2 dozens of practice tests available(6 princeton, 6 manhattan, 4 kaplan, 2 Gmat prep,3 old GMAT tests) with me. I have to take full advantage of these resources but only need right guidance to do so.I am not ambitious about getting 750 or more but i also cannot afford a score below 670!

Ok...
Look, honestly I think taking too many practice tests is NOT going to help.
I think you should review concepts you are weak at. If you are willing to share, I might help you to suggest what all you should work on. And dude, Kaplan is NOT representative at all. Running joke is, kaplan's GMAT is based on a maximum of 700 . I ll suggest take gmatprep1 tomorrow to see where you stand and work your way up from there.

Thanks, i will surely look into your advice, i'll start with error log i made and will work on the questions/areas in which i struggled. I will give my gmat prep1 in a week or so.Ill update you on the same.Thanks

Sure man.
You sound like a man with a plan.
I am sure you will do good!
Cheers

Well it seems like my plan is not working as expected.
Gave Manhattan CAT 1, and got a dismal 640 (Q46 v32) , after all revision and stuff.
I am struggling with speed in quant and especially for tough problems.
Was destroyed by verbal as i was not able to complete my section within 75 minutes resulting in 7 question unanswered.

In lieu of the current situation, I'm planning to postpone my GMAT test date from Sept 7th to Oct 13th!
I'm not sure if postponing the dates will help me in any way but one thing is for sure giving and wasting mock tests won't help me in any way until i improve my speed in both sections.
Any tips to improve speed/accuracy in quant for 700+ problems. My accuracy rate for these questions on an avg. is about 20% when i try within 2 minutes and goes up to 70% when i take more than 5 minutes. The biggest problem is that it takes me almost 1 minute only to understand the freaking problem .

Thanks Abhi for your encouraging thoughts , gonna need lots of them these days.
I am planning to give Gmat Prep 1 in 2-3 days which will help in better introspection and for the time ill try to further analyze my weaknesses. I also admit that there are certain topics/areas in which I am weak eg. combinatorics and probability, some cases of word problems topics, but a tough problem is a tough problem, at-least for me, be it any topic.

Another sad day of my GMAT journey.
GMAT Prep1: 610 (Q48 V26)
Incorrect(quant) 13/37
Incorrect verbal 14/41
Worse thing was that i could not evaluate all my mistakes . The regular household power supply is not always on friendly terms with the common man in India, and with that the GMAT prep software also gave me a surprise by not persisting any information on the test i gave.
Do i need to have retake the same test inorder to review the questions or there is some other way out?

All things aside, my main question is should i give GMAT on 13th, October 2012?
I know this is kind of stupid question to ask as only i can give the most reasonable answer after introspecting myself. I just want to have opinion of experts and peers who might have gone through similar situations or have dealt with students like me. People can always judge and tell , "hey! this seems a bad idea" or "Forget it, lower your expectations" and may be "definitely, 680+ can be achieved in 1 month " .
Target Score
680+
My progress so Far
MGMAT cat1 got 640(q46 v31),
MGMAT 2 660(q44 v35) and
GMat prep 1(610 Q48 v 26).
I found that the questions in MGMAT cat for quant are litle tough but the marking is lenient, where as for the verbal section, i feel the MGMAT gives score on a bit higher sides.

What i studied
Till now i went through OG-12 ,verbal/quant review once.
I used Manhattan strategy guides for verbal (SC, RC, and CR all read 1 time) and took advantage/help of GMAT club resources and members for my quant.
Resources left
I'm left with 4 MGMAT CATs and GMAT prep-2, i have also borrowed PS CR bible from my friend to help me through.

Time i can devote
3 hrs weekdays ; 6hrs week ends ;Total approx. around 140hrs.

Weaknesses i observed
1:) time management , almost 1 question always left in each section every-time; disproportionate time spending on questions.
2:)Oversight mistakes in SC, struggle in CR medium/harder questions.
RC im clue less, always running short on time and end up guessing in panic.My accuracy in attempting RC questions never topped more than 60% be it OG or any other material when done in a timed environment.

I am writing all this just to keep a track of my self and to elicit response and help from the members in form of valuable advice and encouragement. Thank you.
