Plzzzzz Help - acidtest

[ArchivalUser]

I am an IMG with reasonably good scores and took Step 2 CK in July. I want to take Step 3 on 6th and 7th. Just went through USMLE WORLD QS and Crush once. Took NBME and scored 410. Need to prepare for CCS and i have about 11 more days to go. Should I take the exam on schedule or postpone it looking to NBME scores and my brief preparation. USMLESTEPS123 helps or not?? As I have interviews starting just after my step 3 if I postpone it, I can't take it before mid Dec. Is taking Step 3 before IVs that much important?

Plzzzz somebody help me what to do next????

I am totally confused....
