Just ask the school for another copy. They keep copies of absolutely everything, so they'll definitely have a copy of that.
No don't ask the DMV. The DMV is a government office, and government offices don't do stuff for people.
Get used to that, because that's the rule when dealing with any government office / service / authority, and you need to know it. Here's how it works when dealing with any government body...
If you (just for example) miss a line on your tax return, they'll find you. They'll surround your house with white vans and black helicopters, and they'll know everything about you. They'll know where you live, where you work, who all your friends are, your shoe size and what you had for breakfast last Tuesday, so you better tell them the truth because they know every little detail.
But if you need them for something, anything at all, they've never heard of you before. They won't even believe you are who you say you are.
