Online summer programs at Carleton?

I’m thinking about doing one of Carleton’s online summer programs this year. The computer science or art ones were the ones that interested me most. Does anyone know how competitive these programs are to get into? I know you have to have letters of rec and submit a transcript, but how likely are you to get in? Also, would doing these summer classes look good on college apps? It would be great to know anymore information about these courses or the application process!
