Top Resources
FSO Compass
Compass is the predominant online resource to help guide and prepare you to become a diplomat. With courses, practice tests, an online community, and the famous personal narrative challenge. Compass is the membership site for folks who don’t want to go through this process alone.
Department of State
If you’re thinking of becoming an FSO, then you’ll want to make sure to visit the Department of State’s website on the Service.
Grammarly

Grammarly is a grammar checker and proofreading tool that goes beyond its technical purpose – it not only helps check spelling, punctuation, grammar, and sentence structure, but it also offers real-time assistance to improve a content’s clarity, cohesiveness, and fluency, as well as your vocabulary.
Grammarly is great for improving your knowledge for the English Expression section and preparting for the Case Management exercise of the FSOA.
