If your permanent address is with your parents, as I assume it is b/c you are simply living elsewhere during school, I think you would qualify. I can't use my own college experience as an example (my mom moved from CA to FL the week after taking me to WA for college, so I lost "home" entirely), but my brother was still a resident of FL when he went off to NC for college, and would have qualified for WDW's FL resident seasonal passes during that time.
And it would likely be the lowest so cal AP out there, which has MANY blockout dates.
It doesn't matter who bought the tickets, by the way; they can tell how much was paid for them, and they just do the upgrade based on that. So no worries about that!
Check out the blockout dates; make sure you're not planning to go on a blockout date *after* you do the upgrade. If you upgrade then want to go on a blockout date, you'll either have to change your plans, pay $40 for a blockout ticket, or just upgrade your AP to a level that allows you to enter on that date. So be careful with that!
That said, if there's just one blockout date you plan to visit, you can upgrade ON that blocked out day, and they allow you to stay and hop. Any future blockout dates, however, you'd need to do something from the above paragraph.
I will say...if you think you might post about the so cal AP you'll get, I would *highly* recommend changing your location to show that you're just in Chico for school, but you are a so cal resident. Just to save possible unpleasantness or extra explanations.
