Tried not to think too much about it at first but I enrolled in one of their aviation management courses because my daughter kept saying I should learn something new at my age. The training material itself was solid and well structured sha, but some of the instructors seemed like they were just going through the motions without really engaging with us students. I learned what I needed to learn but I expected better interaction and feedback given what they charge for the program. Would recommend if you're serious about self teaching but don't expect to be pushed or mentored closely.
