Materials Needed

  • Scratch papers and writing utensil.
  • R and RStudio installed on your computer.
  • Calculator. A graphing calculator is useful but not necessary. Your calculator should be able to perform:
    • Combinations.
    • Exponents.
    • Logarithms.
    • Etc.

In short, don’t cheat. Any violation will be punished as harshly as possible.


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.

Will the exam be curved?

  • No.

We got our grades back, now will the exam be curved?

  • No. Unless you want it to curved to a normal distribution with a mean of 75. In which, case, sure, that would make my life easier.
