I think I might agree w/ the above...However, you still have almost 15 days and A LOT can be done in 15 days...Have you done COMQUEST/COMBANK yet? Have you finished them?? If you do them or at least COMQUEST completely...try for 100 q a day...then I would retake a comsae...I scored 100 pts higher on the real than on my COMSAE for the STEP 1 COMLEX and I found that they actually do represent well what you will see.
So If you dont think you can get a lot done in 14 days then push it back...But honestly with the score you have now on COMSAE,,,,,I say stick it out..push hard these next few days w Qbanks and you'll be perfectly ready come the 31st.
Good Luck! Trust yourself!
