taking the test in a week but upset about recent low scores

You have great GMAT Prep scores. Go for it. You may be done much earlier than otherwise if you have to retake. Don't kill yourself the last few days before the test.

FYI. If you have less than 7 days left, there is no value in canceling....

Thanks for the feedback. I've decided to proceed with the test. Going to take 2 more CATs this week and rest up a day before the test.

I am still bothered by why my kaplan cat score was so low, and why my overall % is lower than both section%, i didn't know that was possible

Cancellation or postponement is not a wise move in your case, I think. The main obstacle to your score will come from: (1) high stress or anxiety from your "low" scores on the Kaplan and Manhattan CAT, and (2) burnout from doing too many practice tests so near the actual test date. Manhattan tests are tough, and Kaplan has (or at least had) a reputation for their CAT's in terms of difficulty.

You should be fine at this point. Just stay calm and in control. I know that's easier said then done, but this is really the last obstacle between you and a great score (other than the actual test, of course!). So many fall prey to freaking out or doing too much in the last week. Don't succumb to this temptation!

took another mgmat cat today, received 730. I actually knew i messed up on math because i was out of time with 8 questions to go.

I am less concerned about the Kaplan diagnostic now. I think they purposely score lower to induce people to register for their class!

You seem calmer and more relaxed now, so that's good. Just continue to stay in control! And remember to take a break the day before the test in order to be fresh. In fact, you can just as well take two days off.

Good luck!

Thanks for all the positive feedback!

I took my last mgmat cat today with both awas mgmat#6 - 750
even used the test simulation booklet (scratch pad) and marker.

my test is saturday, and i still have gmatprep#2 left.

I was thinking about doing it Thursday, and resting all day Friday.
or
Taking it tomorrow, and either studying lightly or resting Thursday, followed by resting Friday.

What do you guys think is the best approach to peaking my score on the actual exam?

took the gmats today... way under my expectations. q49/v38 - 710.

I am actually feeling pretty worthless right now.
My last few practice exams were mgmat 730/750/730. gmatprep 760/730. (all first time exams under real conditions and no retest material)

In fact my verbal scores were always between 41-45..
I have sub-standard GPA - 3.0. Major gpa 3.4. Although I did have a double major.
I also have average work experience. 4-5 years, 2 management jobs.

I had originally set my eyes on a top 20 school. Now i'm not so sure anymore, and I'm feeling pretty lost as what to do next. I would appreciate any suggestions and feedback.

Thanks
