u/Disastrous-Bill-2375

i have my step 3 day 1 in two days, ive finished uworld (67%avg), ive done as many incorrects as i could before my uworld expired, my uwsa 1 was 207 and uwsa 2 was 220, nbme 7 was 491 andnbme 6 offline was 71% and free 137 was 68%. Ive done all of the ccs cases and my average was 75%. I dont know how to go about my prep for the remaining 3 days, alot of talk on here is that it's mostly step1 so i went through some drug mechanisms and some immunology stuff, my question is should i do the old 137? i took uwsa in april and early may, so im a little nervous going into the exam
