GMAT 1st attempt 580 (Q46, V24) Too bad to be real

Hello everyone,

I'm on this forum for a while, so some of you already know me. I gave GMAT a first try today to score miserable 580. To be honest, considering my mental condition at the moment, I would most like to write nothing at all, but I won't give up and would appreciate some advice from you. First, I'll provide some hard facts about my preparation. Second, I'll share my observations about my weaknesses. Finally, I would kindly ask you to share your experience.

I've been pretty strong in quant since the beginning, so I concentrated on the verbal part. Below you can find some CAT results. In quant the range was 47-51, in verbal 34-36.
I've done all questions from OG and Quant review and Verbal review. Moreover, I've downloaded an extract from GMATprep software from Carcass and went through 70% of all the questions both verbal/quant and had a very good accuracy (84-92%)

-800Score ONLY QUANT CAT1 51, CAT2 50, CAT3 50
-GMAT PREP 670
-MGMAT CAT 630
-KAPLAN CAT 660

My observations about the weaknesses

1. While going through a particular topic in quant, I can solve literally any 700, 700+ question, but after some time I just forget the concepts and when faced with a 600-700 question I stumble.
Question: How to maintain a given level till the exam ? Most of us learn during the week just 1-3 Hours and 5-6 Hours on weekend, so it's very difficult to do some drills pro question type. There is simply not enough time to do so.

2. I've done only few full length CATs --> Stamina

3. Reading comprehension is the most weak part in verbal in my case. I've been pretty good on SC and CR


Test Day

Timing
-I've finished both parts in time with just 20-30 left. I had absolutely no problems with timing during the exam, although I did only few CATs before.

Quant
- Hmm.... As I've already mentioned above, I've done lots, and I mean really lots of OFFICIAL quant questions, but I can say for sure, that the questions in the guides and GMATprep are not representative any more. I would say only 30%-40% was similiar to what I've alredy done or seen before. I had a verly low quant score this time (Q46) and this reuslts from the unusual question types I've been faced today.

Verbal
- Verbal was similiar to GMATprep, BUT the text itself in both SC and CR was very, very complex and difficult to digest. It was a shock for me to see V24..... I've been never below 35. But to be honest, because of some unrelated factors + few full length CAT - I think here was stamina at issue, I was very tired on that day, so that after question number 20 on the verbal part, I could't see anything. I was just like under alcohol influence.

AWA
- Didn't look at it till the last day before the exam, and guess what, I saw exactly the text from the collection of 109 essays, which I've downloaded from this website

Right now, I just don't even want to think about retaking... I'm just dead tired after almost 3 month of preparation and moreover, I don't think that my family and my friends would be delighted to forget about me the next month or two. But I won't give up and would appreciate any ideas, suggestions etc.

Thanks in advance.
Spasibo.
