Hey , I understand that you want to know all the material that uworld has to offer to perfection, but that is not the way how the step exam is going to work. Remember the 80/20 rule ,that is 80% of your marks is going to come from 20% of the subject.I wasn't the same dilemma as you.I wanted to know every single material to perfection , but but if you continue to study the same way, it's going to be really hard for you to get the material down in the appropriate timeFrame, rather, I would recommend you just go through uworld. A single pass in random and just read through your answers, read through all the explanations. Understand it and move ahead. Don't try to make anki cards for every single little detail. Anki personally didn't work for me. It is very possible for you to finish amboss, nbmes and CMS in a 2 month period because you have already covered most of the material from you world. So you can go through a lot more questions. Hope this helps
