I start college in a few months but my retail job is draining me dry

Hello! I work at a tech store and it's one of the worst jobs I've been through in my 3 years of retail experience of being a front end register guy. We barely get anything to do and managers love to talk down to not only us but other departments too, It's come to the point where they are thinking about taking tasks away from front end because sales floor as nothing to do? Even though they have plenty to do. There were other things these guys did but I won't get into that now. I'm finally leaving this place and starting college in a few months. But this job is slowly breaking me and almost at my tipping point to just quit and I don't want to do that as I need savings for College and I don't think any other place is willing to hire me just for me to leave a few months later. If anyone has any tricks on how to get through those 2 months with this job or any other ideas that'll be great. Thank you for your time!
