ZedFR, why are you so angry kiddo? No one asked for your input. If you're going to speak out about something you don't understand, don't incorporate yourself into the situation.

being so ignorant about something you teach is literally scam, like these guys promising you you are gonna learn how to code in 4 days

you too take the CS50's Harvard course on edX, you need it as much as someone without upfront knowledge

thanks!!!
