General GMAT Questions and Strategies | Re: GMAT score 690 should I try again?

Thank you so much for your answer
I got Q47 and V38. I am not an English native speaker so improve Quant score would be easier to me.
Normally my test scores were around 700: 46-48 quant and 38-40V. So 690 is a fair level for me, not too far from my practice tests.
I work 8 hours a day and sometimes I have to bring my work home to finish so I can only study for 1-2 hours per weekday and 5-6 hours on Sat/Sun.
