Get mentored the Standard ML way

Every language has its own way of doing things. Standard ML is no different. Our mentors will help you learn to think like a Standard ML developer and how to write idiomatic code in Standard ML. Once you've solved an exercise, submit it to our volunteer team, and they'll give you hints, ideas, and feedback on how to make it feel more like what you'd normally see in Standard ML - they'll help you discover the things you don't know that you don't know.
