Thanks for the responses.
I currently work in Management Consulting and will continue my studying while working.
My weakest area is definitely Quant. Though something went very very wrong on my Verbal section during my actual GMAT test. Here are the results from my practice tests and actual test broken down:
Date Overall Score Quant Verbal
Economist 20/07/2019 590 34 (25) 37 (82)
Kaplan 03/08/2019 590 37 (40) 34 (71)
GMAT Site 1 06/09/2019 590 3 (25) 38 (85)
Manhattan Prep 09/09/2019 630 44 (52) 32 (66)
Veritas Prep 13/09/2019 620 39 36
GMAT site 2 21/09/2019 640 42 (45) 35 (76)
Real GMAT 24/10/2019 540 36 28
I'm also open to suggestions on best study program to use online. I've been thinking of
Magoosh or Manhattan Review. I've got some basics down as I've already been studying for 3 months and scoring around 630 on practice tests.
