Misdirected answers

I just got a text message from a number I don’t recognize… three of them, actually. The first one starts out:

Chemistry answers 1a 2c 3a 4b 5b 6c 7e 8c… 

And goes on like that over the course of three messages, all the way up to answer #77.

I considered texting back “Wrong number!” but that would make me a party to cheating. Looks like someone is going to fail their Chemistry final!
