Questions

How do you check if your prologue is submitted properly?

Ask Sam.

Generally, you should write your prologue in a separate document and then copy and paste.

Make a bad joke and see if I respond.

What are the hardest (most time consuming) problems?

3 and 6. 5 is either easy or impossible. Think about them all early so that you can reflect on them while dancing at Blackout.

Can I make random numbers that are negative?

Yes. Do the reading and lab. Then ask me.
