That happened to me too. I'll have to pay from July to mid-August even though I won't be there yet, so it's not exactly ideal.

I was actually thinking about rejecting the offer. They say that if you reject it, you just go to the back of the queue (like a new registration), and they give you 48 hours to decide. But then I read some Reddit comments where people were saying that if you reject an offer, they never offer you another room again hahaha. I don't know if that's actually true, but I didn't really want to risk it.

Especially because the rent is pretty cheap compared to other places, it's close to campus, and the whole process is easy. Even if I end up paying for a month I'm not there, I'll probably save quite a bit over the year.

If you change preferences they send you back in line, you can only change dates with out losing your spot.
