How to ask what days of the week someone does something


How would I ask some "What days of the week do you go to school?" Would
"なんようび、がっこうへいきますか" be a correct translation?

Correct! And, 「なんようびに」that is commented by boccoli forest is better.  
If the questioner knows that you go to school mulitiple times in a week, the
natural ways of asking are;

>   * なんようとなんように、がっこうへいきますか？
>   * がっこうへいくの、なんようとなんようなの？
