Hi David,
why not taking this as a own project? Do a plan and do a schedule. You have the end date (in January or may be in decemeber if this works better for you).
Now plan backwards and see if there is enough time or just plan forwards and see if time is enough and if not, than apply scheduling technics like fast tracking, crashing and so on ...
What i wanna say: there is not really a shortcut!
You may take a little risk, focus on some areas and leave others aside. May be you got lucky and take it down ... but what if not?!. Than you have a much bigger problem since you have only one shot, cause after this exam changes significantly and you have to restart new, right.
Well, just act like a pro! Take it serious, do a plan and stick to it!
