Hi taliyev,
First of all, congrats on the 710! To help you determine whether you should retake the GMAT, I would like to learn some more about your GMAT experience and MBA goals.
1) What is your quant score goal?
2) Did you get your enhanced score report? If not, could you do so and share the score breakdown from your GMAT?
3) Have you taken any official MBA.com exams? If so, what are the score breakdowns of those exams? When you took the practice tests, did you take them under realistic test-day conditions (e.g. in a quiet environment, no extended breaks)?
4) What is your study routine? For how many hours a day have you been studying and for how many total months?
5) For how many hours a day can you study for your retake?
6) What deadlines are you targeting?
You may find it beneficial to reach out to some [url=https://gmatclub.com/forum/ask-admission-consultants-124/] admissions consultants here on GMAT Club[url/] to determine whether your GMAT score is sufficient for the schools to which you plan to apply.
Once you respond with the information above, I’ll be happy to provide some more tailored advice. If you need anything in the meantime, feel free to reach out to me directly.
Good luck!!
