Hello,
I would like to know, if I only focus on FA and UW, would be enough for the exam and mostly for Path, If I know these two sources very well. Would you please let me know based on your experience if I need to any other sources ( like extra book, or question banks)?
Thanks

UW and First Aid are good sources, yo may also want to try a different Qbank like USMLE Rx or Kaplan Qbank, just to familiarize yourself with different types of questions.
