gre2GRE

I gave my gre and got 152/162/3.5(v/q/a).I want to apply to top tier schools and have also given a gre subject(chemistry) in which i believe i will get 80+ percentile.I was thinking of a GRE general retake but, the prometric center has all the seats filled and is not showing an appointment before Decemeber 1st. Considering the fact that I am applying to schools with deadlines around December 15, would it be a good idea to take a GRE on 1st December. The other date that is available is 12th November which leaves me with about 10 days for preparation.
