I did UWSA 1 about 3 weeks ago and my score was a 214 (overall 59.5% correct) and today I took UWSA 2 and I received a 211 (64.25% correct). How does UWorld's UWSA exams come up with the numbers to predict score on actual exam and is it possible for me to get a 220 on exam day? My exam is in 6 days on Sunday!

Please let me know!! any help and advice appreciated on what I should do in the next 6 days to bump up score!
