Hi! ❤️ so it would mean a lot if anyone could give suggestions or anything!

So I am in college, I’m a full time student taking 14 credits. I have been offered a job that requires you to work 18-22 hrs a week. On top of that, I am in debate as my extra curricular (which meets 3 hrs, 2 days a week) I am just asking if this sounds like a lot to do? Or if it sounds doble? How meant hours have you guys worked while being in college? Thank you !
