Baseline score 400, targeting 650

Hi,

I am new to GMAT CLUB and it has been around a couple of weeks since I started my GMAT prep. I am 32 and planning to take a break for a year and do my MBA. Going by the posts here, I saw most of them are targeting a score of 700. But I have soon realised that 700 is not my cup of tea and given my experience and profile a few colleges have said I can make through with if I am around the 650-mark.
I have been looking at sub600 questions on the gmatclub and have not got any wrong, but it is the level above that seems too difficult.
I am not an IT or Engineering student and have never been inclined towards maths. Having said that, my basic concepts are clear.

So, coming back to the question, how do I study quants to get anything 45.

For Verbal I am not too worried but have seen many struggle go beyond 40. So I am being realistic and targeting 35. ALL INPUTS AND SUGGESTIONS ARE WELCOME.

THANKS IN ADVANCE

P.S I am being realistic in my approach and am targeting the 2021 intake
