By the time you go back to school in the fall he will be around 5 months old, which means he should be able to hold it for 6 hours. I assume that you will gone longer than that, so crating is not really an option. You really don't want him messing in his crate and I wouldn't want to force him into having to do that. :( I think the kitchen or the bathroom would be better options. You can get some really long gates at pet supply places. I would still crate train him though as it's really important that your pup be comfortable in a crate, if only for when he may have to stay at the vet for any reason.
I personally wouldn't want him going out into the back yard unattended when you are not home. There is just too much danger of him escaping or having him stolen.
Good luck with your pup!
