Hi Sanji,
The scoring algorithm on the Official GMAT is far more complicated than most people realize - and it factors in more than just the number of correct and incorrect answers. It's also worth noting that some of the questions on your Exam are "Experimental", meaning that they do NOT count towards your Score. Unfortunately, there is no way to know for sure which ones are the Experimental ones (since they are written in the same style as the other questions that 'count'). Thus, as you compared these two CAT performances, it's possible that when you got more questions wrong in the Quant section, you actually got a number of the Experimental questions wrong.
The more relevant question is whether you are happy with a Q44 or not (since you've scored at this same level on back-to-back Exams). If you're looking to score notably higher, then before I can offer you any advice for your studies, it would help if you could provide a bit more information on how you've been studying and your goals:
Studies:
1) How long have you studied? How many hours do you typically study each week?
2) What study materials have you used so far?
3) On what dates (or approximate dates) did you take EACH of your CATs/mocks and how did you score on EACH (including the Quant and Verbal Scaled Scores for EACH)?
Goals:
4) What is your overall goal score?
5) When are you planning to apply to Business School and what Schools are you planning to apply to?
