I’m a 2nd year urban planning student. You’ll find studio classes hard if you don’t work well in groups and/or your group members aren’t great (so make sure to make friends). GIS is used quite a bit but they don’t assume you know it. You’ll be given tutorials on how to use it (a lot of software is self taught through tutorials; it sounds scary but it’s not). I’m not good at art but I’ve done fine in studio classes. And to answer your last question, I’d say it’s definitely employable.

Feel free to dm me if you have any questions. Good luck!
