Slow march towards more than 250 points increase

Hi,

310-380-480-510

Actual gmat on may 2014 - 490

I am aspiring for MS (one of the courses offered under business school ).My target is 620.
The school requires average of 600 for the program.

Actually my review is too early to write. I consider myself average learner.when i started my gmat preperation, i thought gmat to be easy just by going through mgmat books for few days.Main drawback was i never prepare at a stretch. initally my preparation was for 20 days then i gave gmat prep - 1 exam. there my total life got struck scoring only 310 ( 29 q 8 v ). Then i decided to join e-gmat verbal live prep after attending one free strategy session.
Huge materials organised in structure and excellent live sessions by egmat helped me to increase my score from v8 to v25.though the name says live prep, you will even have recordings given after each and every session. students who cant take the live session,can watch the recordings. sessions of Payal and shraddha created hope in me that i could achieve v30 easily. Then with the help of gmat club test ( i know they advise only for 47 and above . Got free access along with e-gmat live prep) i increased my quant to 36. Mean while i did take few practise test in between
GMAT Prep 1 - 310 ( q29 v8 )
GMAT Prep 2 - 380 q32 V11) Then after e-gmat course my verbal went up to V25.I did take up MGMAT test, kaplan practise test and 800 score.com test. Irony is the real scores matched my gmat prep and not MGMAT. MGMAT test i took 2 test out of 6 and in those test i scored more than 550 especially verbal going upto 32.
MGMAT 1 - 580 ( q37 v 32 )
MGMAT 2 - 560 ( q 36 v 31 )

GMAT prep 3 before the test day - 510 ( q 36 v 24 )

Finally when i gave my test on may 2014, started my quants with 30 sec delay due to extended break. The whole section went in total hurry. throughout my practise exams i never had to guess last 5 qns. it was always on time or even finished it earlier. but on d-day the last 5 to 6 qns i dunno wat qns were asked bt i knew only 3 mins left and i will have to select the choices before time lapses. verbal went smooth.
The score was shocking 490 ( q 39 v 19 ). i couldnt believe how accurate gmat prep was. my friends and gmat club post said it is very rare to see score more than gmat prep. it would always be -20 to -30 from the gmat prep test. I decided to take a break and then retake the test. It was long break. Again i thought i will take up by dec. so joined e-gmat quant live prep by aug. Japinder was excellent in live sessions.
I finished quant live prep within one month. though i joined by aug, i dint start til dec end.
I gave GMAT Prep 1 jan 6 480 ( q 36 v 23 )
Then after the quant classes i gave MGMAT practise test
JAN 20 - MGMAT 3 - 570 ( q 41 v 27 ). The point to be noted is i did not touch verbal after may 2014.i started practising on and off
GMAT Prep 2-feb 2 560 ( q 42 v 25 ). Now i am left with 25 days for the d day and need 80 point increase.I have got more than 50% to finish in og 13 and Verbal 2nd edition.
Any suggestions or points to be noted in last month, please advise.
the point of writing review is to suggest choose proper materials and invest your money wisely on good prep course. thanks to GMAT club for constantly reviewing Gmat courses.That helped me to choose e-gmat and here i am marching towards 600. for many 600 would have been the starting point. But there are lot of people like me whose dream is to score in 600's. Hope i achieve it in 25 days.
