  - There are NO solutions to these problems, only answers. You must come to the review or see me to see how to work the problems.
  - You should be able to do these 34 problems in 80 minutes.
  - The actual final has 42 questions. It is 38% new material (16/42 questions) and 62% old material.
  - This is the information page you will get with the exam. It consists of 3 pages with a PT, useful info and equations. You are NOT allowed to bring a help sheet.
    For more information about the final see the Exams link.
  - The following are reminders for the exam.
    - The exam is 105 minutes. The window in which you can start the exam is 2:00-3:45 PM. However, you MUST finish by 3:45 PM. Carmen will shut off your access to the exam at 3:45. That means since the exam is 105 minutes you need to start at 2:00 PM if you want the full 105 minutes.
    - You MUST use an allowed calculator with cover removed and put away.
    - NO HATS, HEAD BANDS, OR OTHER HEAD COVERINGS! (except for religious reasons - see Dr. Zellmer before the exam). They must be removed.

    - NO food or drinks, unless medically required (see Dr. Zellmer beforehand).

```
  - Your ID will be collected when the scratch paper is passed out. It will returned when you return the scratch paper to the TA.
- Solutions to New Material problems - overheads from a previous review. These could be a little different than what we actually cover in the review and I suggest you come to the review. I will record the review in Zoom and send the link.
