The UC Riverside Biological Sciences Graduate Division has officially lost 2 of my transcripts, GRE scores, supplementary application information, check, fellowship application, and 1 (of 3 total) letter of recommendation.

5 separate envelopes. 2 of which sent from outside the state of California.

They tell me it's all lost in the mail. "If you sent it certified, we might be able to track it."
I didn't.

Let's have this be a lesson for all of us:
Choose to mail everything certified.

Oh, and... Don't plan on getting small-school attention from UC Riverside. No matter how small the program is that you're applying to, the school is massive and you can still fall through the cracks.
