Yup, it is doable. I haven't gotten my step 1 score yet but I'm assuming the score report is similar to an NBME? If yes, then look at your weaknesses and focus on those. If you feel that redoing (I'm assuming you did uworld once, if not then that's a big area to focus on of course) Uworld will help, then go for it. Take more nbme's to see where you're at. Good luck 😀
