How do I go from here? Stuck at 600/620

[monikajudd]

1.
6 months back I took my very first diagnostic test without preparing for the GMAT.
I took a Manhattan GMAT CAT and scored 530 ( Quant - 33, Verbal - 30)

2.
I bought the Manhattan Guides and read them all (did not do the OG questions) and took a second MGMAT CAT. I messed up on my timing pretty bad on this test.
I scored 600 ( Quant - 39, Verbal - 34).

3.
After I gave this 2nd CAT, I solved the Official Guide verbal and math questions and took a GMAPrep CAT. I did way better with my timing on this test.
I scored a 620 (Quant - 40, Verbal - 35).

I don't know what I am doing wrong. I am disappointed since I thought that after spending a month solving all the questions in the OG I would score much better.

Where do I go from here? My aim is to score a 720 or so.

Should I enroll in a GMAT Prep class with ManhattanGMAT etc? What other resources can I use to boost my score? My Quant scores are pretty bad although my verbal are not great either.

Thanks a lot for pointers.

Hi Monika,

I wouldn't necessarily say that you're stuck at 600/620. I might draw that conclusion if your last 5 tests were at the same level, but it might be too early to use the word "stuck." You may have just had an off day.

I suggest that you take another practice test in a week or two and see if you are, in fact, stuck.

Cheers,
Brent
