Hi Amit700,
GMAC has publicly stated that the Official Score that you earn on Test Day is within +/- 30 points of actual ability. Assuming a similar 'swing' in how your CATs function, your CAT score results going back to November, 2019 - and your Official Score - show that you essentially performed the same each time (about 430 +/- a few points). You handle certain aspects of the GMAT consistently well, but you also make certain consistent mistakes. Since you have been performing at this same general level for over a year, it is likely that you have developed some 'bad habits' that are keeping you from scoring higher. Before you can consistently score at a higher level, we need to fix those habits (and replace them with new 'good habits'). By extension, continuing to work through 100s and 100s of additional practice questions (using the same approaches that you used over the last year) will probably NOT lead to a big improvement.
Statistically-speaking, raising a 430 to the point that you can consistently score 650+ will likely require that you commit to at least another 3 months of consistent, guided study - and you'll have to make significant improvements to how you handle BOTH the Quant and Verbal sections. Thankfully, the GMAT is a consistent, predictable Exam, so you CAN train to score at a higher level.
Before I can offer you any additional advice for your studies, it would help if you could provide a bit more information on how you've been studying and your goals:
1) Over the last 3 months, how many hours did you typically study each week?
2) For your next attempt, are you planning to take the At-home GMAT or are you planning to take your GMAT at a Test Facility?
3) What Schools are you planning to apply to and what specific application deadlines are you facing?
You might also choose to purchase the Enhanced Score Report. While the ESR doesn’t provide a lot of information, there are usually a few data points that we can use to define what went wrong on Test Day (and what you should work on to score higher). If you purchase the ESR, then I'll be happy to analyze it for you.
GMAT assassins aren't born, they're made,
