I got my score 2 weeks ago and I had not the chance to talk about my experience.
Step1 & and 2 CS done before CK
Time of preparation 6 months
Source: UW ONLY !! (done UW twice)
First-round UW - 74% 2nd round - 84%
NBME 7: 224 (9 weeks before)
UWSA1: 264 (6 weeks before)
UWSA2: 255 (2 weeks before)
In general, there is nothing more than UW you can do. If you want to add anything I would suggest to solve the NBMEs and CMS.
Advice to exam: sleep very well, try to understand that the exam is 9 hours and you need to have stamina to the last second
The time is not as step1, you need to be quicker.
Goodluck to everyone wish you all the best
please no DM , any question ask in public
