Crashed From 660 in GMAT prep to Actual GMAT 510 (Q39,V21)

[leokashyup]

It is such a heart break! I was doing really well with my practice exams scoring about 670 max to 580 min. And with the real thing :
1.I had timing issues in verbal section during my practice tests, ending up guessing the last few questions. In the real thing, I made sure i was awake and on and finished the section with 5 mins to spare. Felt questions were easy, did not challenge me.
2. Never had any trouble in quants during my practice tests, scoring on avg 46 and finishing on time. In the real thing, finished the quant section with almost 10 mins to spare. Felt the questions were easy, few were nice ones.
3. I have been prepping for the past 3 months.

Materials used :
OG 12
Kaplan Premier program
Princeton Review (i thought was a waste)
OG verbal, Kaplan Verbal Review
Kaplan Quant
Kaplan 800
Manhattan SC
Sahil SC notes

Few things, I took the MGMAT Tests each day, the week before the real thing to build my stamina. Thought MGMAT tests would have added better value to my prep, if i had them earlier.
Guys, I have an urge/temptation to take the test as early as first week of oct to prove a thing to myself (call it ego). Your inputs would be of great value to me.

Hi

Sorry to hear about the unexpected results. CAn you list out all mock tests you took and scores you got for each.?
The range of your mock tests looks like a big swing, but maybe you tried different tests.

If you had so much time spare in the quant section, looks like you might have made a good amount of careless mistakes. Sometimes nerves comes into play. You need to look at your scores break up and decide where you need improvement. Certainly take it again, you might do better than 670. But give it when you are clearly consistent in your mocks.
