I'll try not to sugar-coat anything here, because that's not going to help: Yes, that's low. But you can change it substantially in the next two months, especially since this 35% is your very first UWorld experience ever.
A couple things that would misrepresentingly lower your score:
-Doing the Q's on random when you haven't completed every block in your classes
-Not reading the material you're about to do Q's on (most people do)
-Running out of time on the UWorld test you took (the minor problem of slow test-taking is far less serious than a disparity of knowledge and can have severe effects on your UWorld test %)
Follow the advice of people on this forum. Systematically go through FA, then do the corresponding UWorld. At your point, I'd say you want to master FA and UWorld as much as you can before branching out to other resources (but if you don't understand something in FA or it's not sticking, use other resources). Read every UWorld explanation completely if you didn't know the answer, and understand entirely why your answer was wrong and the right one was right. If you 100% knew the answer, still read the UWorld learning objective. Annotate it all into FA and try and get 3x reads of FA in the end. Getting through UWorld completely is a must.
You can do this. You have hundreds of man hours to prepare. Let any fear and doubt push you harder.
