# MDM4U – reference page

I forgot to mention in the “test tomorrow” post: you can bring a one-sided, handwritten, quarter sheet reference page to your test. You might want a formula for $P(n,r)$ for example.

I’ll reiterate the purpose of the reference sheet. It’s for remembering the fiddly things that you might look up in real life. It’s not for learning the course while you’re writing a test. There won’t be time for that.

You can’t photocopy each others’ reference sheets, either. Make one yourself and learn from the exercise.
