Hello! I’m an IMG as well and I recently did my Step 1 and scored 260. This advice is based on my experience only so take what applies to you
The most important ones would be UFAP- Uworld, First Aid and Pathoma. Boards and Beyond was a good resource as well that can be used to supplement UFAP. Doing NBME exams are also important to gauge your level of prep.
Depending on the amount of time you have for taking the exam, you can try the following:
1. Baseline NBME assessment since you’re a recent graduate
2. First pass of First aid and pathoma
- Do questions by topic in Uworld
- Use Boards and Beyond for difficult concepts
- Consolidate notes on first aid & write own notes
3. Focus on remembering content and do Uworld questions on timed mode (all topics in random)
- During this time, focus on reviewing difficult concepts, reviewing content from UFAP
- Uworld questions: go through them more thoroughly, including all options and explanations
- Allocate time for NBMEs periodically to gauge progress
At the end of the day, the sources you use depends on your style of studying. You can always change up your schedules and methods based on feedback on NBME assessments
Hope this helps and all the best for your prep!
