Tell Professor Flitwack to ask your classmate (and tell your classmate that if he won’t tell the truth, you will.)
Tell Professor Flitwack the truth. If your classmate is willing to come in first by cheating, he deserves to be found out. You’ll make up the House points your classmate loses by coming in first.
Lie and say you don’t know (but hope he finds out somehow)
If you knew someone was cheating, you wouldn’t wait for Flitwack to ask; you’d tell him before the test started.
Here's an interesting quiz for you.
