11.5.7 Frequently Asked Questions

How many problems are on the exam?

  • This question is irrelevant since each problem could have an arbitrary number of parts. A one problem exam could easily be written to be longer than a ten problem exam.

How long will it take to do the exam?

  • If you are well prepared and manage your time efficiently: Under 110 minutes.
  • If you are ill prepared or manage your time poorly: Over 110 minutes.
  • You should not focus on this. Focus on practicing and being able to do questions of the types you’ve seen on homework. Let me worry about this. And believe me, I worry about this a lot.
