PMP exam on 15-Jan. Need suggestion on practice exam score

HI All,
I am planning to give exam on 15-Jan-18.

So far my practice exam score are as below:

Rita's PM Fastrack (3th Dec) -- 79.5 %
Lehmann 75(5th Dec) - 74.6 %. But took 7 more mins to complete the exam. 5 answers were left when timed up. Considering that, score goes down to 68%.

Are my scores ok? Any expert inputs/suggestions to plan better remaining days before exam.
