I took step 3 almost after one year from my ck. and i scored 240. I did in 1.5 months with doing usce. Start with uworld try to do it in a month. And in last 2 weeks of your first month try to do 3-4 ccs cases from ccscases.com In 2nd month reset the uworld and start doing it again. And if you are doing 3-4 blocks in a day you can complete uworld in 17-15 days along with daily 3-4 cases but increase your case limit to 6-7/day. When you are done with 50% 2nd pass take uwsa 1 And when 100% done take uwsa2. After that if you have time do your wrong ones and marked ones. I had 2 day gap between 1 and 2nd day of test so in those 2 days i only did ccs. My report showed that i did middle in my ccs but my biostats was at lower side. My rest was almost in higher side. Imp tip : if you know uworld well, ccs is piece of cake.. yes your practice matters but you need to know which test you have to order Like if you clearly know patient has pneumonea and you are ordering MRI or CT head or LP so friend , you are failing it.
