I am an IMG passed long time back. I am preparing for step1 using UW and FA. I have done UW 3-4 times and can do nearly 90% questions correct on it . I also took UWorld self assessments test 2 weeks back with a score of 240. yesterday I took NBME 12 with a score of 310 and corresponding usmle score of 188...feeling depressed with totally shattered confidence. How should I start studying again and what to study?? how can I improve?
