If I start studying now can I still get a 5 on AP Comp. Gov??

So I’ve been procrastinating and as of now I only have a semi-strong understanding of 3 of the 6 countries and a somewhat mediocre undertanding of the vocabulary required. Can I still get a 5 with the decent foundation I have now if I work hard the next 2 months? Anybody here got any 1 or 2 month cramming stories to get me motivated?
