Thanks everyone for reply.
To answer some of the questions:
I'm studying since Jan 2021 (very on and off), but started properly in March. Had planned to write the exam by May, but due to high work pressure, exam pressure, and health concerns, I was asked to take a break for some time. So now I'm trying to pace things up a little. I have used Jamboree Material, but my score in mocks varied a lot (probably because I was being too hard on myself and wasn't taking enough breaks). I have scored 670-730 in mocks but not very satisfied because even after practicing so much, I am still not able to get a stable score. My quant was Q47-50 and verbal was V34-38. I scored 750 (Q49, V42) in my official mock test on mba.com, but this was in May. I was /am still not confident (I don't know what should I do to boost this up though). My score in
GMAT club tests was Q44-48 and V25-35 (but this was in March).
I am aiming for 750 and planning to apply this year or next. I'm aiming for the top 10 US/Canada B schools but have just 2 years of work experience so not sure if I will get anything this year. I just want to give GMAT as soon as possible so that I can get rid of this extra pressure. I work 15-16hrs a day, so try to spend 1-2 hr max on weekdays and ~5-6 hrs on weekends.
Any suggestions on how to deal with this extra pressure, gain confidence and improve score will be very much helpful. Any study plan would be helpful too (RC / CR especially).
