2 months in the GMAT Cave = 530 to 750! (Q48/V46/6.0)

Congrats - I can appreciate how tedious the GMAT studying can be - great to get it done & dusted

If it helps anyone, my experience is that I got a 680 then a 690 in the real GMAT test after studying with Kaplan - despite regularly scoring higher in the Kaplan practice tests - from which I concluded that the Kaplan practice tests were not quite reflective of the actual thing - particularly the numeric

I felt I was capable of a better score so gave it one more shot, but this time I used the Manhattan materials - specifically to help with the numeric. I found their numeric questions were harder and I think that helped, and their text books a lot more detailed - I didn't have time to do all of it but focussed on the areas where I was weakest. Also I did all the questions in the purple OG book which I think definitely helped - I'd definitely recommed doing all of those

After that I sat it one last time and managed to get a 740 which was better than I'd expected & very satisfying after all the work! Pleased I persevered with it

Overall my advice would be not to under-estimate the GMAT and allow plenty of time to study and do the exam. I'd even build in time ahead of your applications for a re-sit if you can - most schools don't seem to hold it against you if you re-sit - they just want the score for their ranking averages I think. Definitely go through everything in the OG as that should be most reflective of the real questions. In terms of courses, Kaplan was more straight forward with less material and suitable if you're looking to score in the 600s. If you want 700+ I think Manhattan is better, but there's a lot of material so you'll need to allow plenty of time to study it (ideally I'd say 6 months to a year in advance if you're able to plan that far ahead)
