I am a teacher. Last year, I was given an assignment to teach my math students excel. So, I have to know how it works, how can I teach my elementary students basic features of excel. I am not a good computer guy, so I consult CCC for training, they taught me many features of excel that helps allot while I taught my students. Personal co-operation is the best thing in CCC. You would feel home while learning. I will give them 5 star for Quality and Value.
