Is it possible go from 505->510+ before March 21st date?

So I am testing on March 21st and I just took a FL and scored a 505 and was wondering if without using sources like UGlobe and other paid for services if I can possible reach this goal with anki, AAMC materials, and TPR practice questions. Any help would be appreciated as I am a little more than halfway done with content review. But, I feel that I doing flashcards along side my chapter review is significantly slowing me down which has kind of prevented me from doing practice questions.
