That obviously depends on, among other things, how much of a stretch the 690 was, how rusty you are from that five months and how busy your schedule is with other things.hmgp22 wrote:How difficult would it be to improve 30 points from a 690 within a few weeks of studying?
I haven't touched the GMAT for 5 months though.
Overall, does not sound so difficult to me.
Just find some areas you can improve in that have high returns on time invested in doing so and work on them.
Each improvement you make could translate to an about 5 - 10 point score increase.
Psychology is huge too. Even just a change in attitude or psychological approach could be worth tens of points. Even better timing could conceivably make a 30 point difference.
One thing you could do is find a good question bank like those from Veritas, Bellcurves Quant, or maybe Magoosh, and just do question after question until you are a pro.
