I attended wiseprep as a senior in high school and it really helped me improve my SAT scores and write high quality college applications. They only hire the best teachers to teach their classes.
I went there for the Codemakers beginners camp and it was very educational. They make sure kids dont have WiFi so they cant play games. In the morning they have lessons and in the afternoon they have hands on programming. It was a great experience overall and a fun one too.
