I have been preparing myself for the last 2 months, and I also thought if i gave my all then I can see like 200 points improvement. Although I didn't have 9-10 hours a day (that's not feasible for anyone anyway nor would I suggest it as it ll burn you up and also if results are not there after that, it ll only lead to demotivation). But regardless, what I realised is a lot of the things are conceptual in GMAT in the end of the day and maybe you can cover the syllabus per say but until you review all the questions you do, you know how to approach every question as soon as you see the question in DI and Quant and to develop reasoning skills in Verbal is not something which is linear. It ll happen overtime. So you need to apply concepts everyday and know what to apply, if one does feel they can just crack the code of every GMAT question I mean they ll be really talented and maybe their initial score would already be 615 or 625 for the first official mock attempt.
Over the 2 months, I have got a 100 points improvement no doubt and that too consistenly but still specially in DI and Verbal I have good and bad days as I myself didn't think of this initially. I ll go to give the exam regardless to see how I do in actual test in the center but I think I ll prepare another month before I say that is my final attempt.
In short, my advice to you start preparing but don't get demotivated if you don't see that kind of jump that you are looking for, I also got 50 points jump like in a week or 2 but after that it was inconsistent. I have also seen 150 point jump once, but that was an outlier so clearly conceptually I still have some gaps. I truly believe after 685 it is a matter of luck as well, but the journey from 605 to getting 685 consistenly is not an easy one if your intial score does indicate that you are below average. (I was the same).
I am seeing 625 in my tests, my first (not official though) was 525 on
Magoosh, then my first official mock which i gave after 10-12 days of studying gave me a 575. Since then I have been around this only a 595 followed by a 625 but then a 595 again, but after that consistently a 625, once I got a 675 on E-GMAT and I thought I am there just to be brought down back to a 625 by the official mock but clearly there is a lot more to GMAT then just solving questions. The algorithm, the way you attempt the exam, the time management skills there is so much going on. You need to also work on those factors which won't come to you by putting hours in.
I myself suffer from test anxiety, so if you don't have that maybe you can do it. But even though i ll see a 90%+ accuracy on practice sets, the best I have achieved on official mocks is like a 80%. But it also takes into play the kind of question you got wrong so maybe even having a 90% accuracy might give you a same score. Again coming back to the point of concept, each and every concept you should know so that you don't miss the easier or the medium ones.

Thank you for your suggestions. I have pushed the paper by 1 month. (Can’t give one post that, because of some prior commitments).
But in these 45 days, I can put 9-10 hours everyday. So I have 400 - 450 Hours with me.
Please suggest what all i should be doing to get a 300 score Jump.
