What users say
Reviewers find it comprehensive and well-suited to teacher-led school programs, but poorly suited to solo learners.
“CodeHS is a good tool for schools to integrate into their curricula, but it's less useful if you're an individual looking to learn on your own”
“using CodeHS alone and expecting students to work in isolation is dehumanizing and will teach them very little”
“CodeHS is solid for coding and computer science education. Its course library is relatively varied in terms of subjects, programming languages, experience”
