OpenLab assignment: practice exam

December 9, 2022 / / 1 Comment

Due Monday, December 19

The final exam has 9 questions; you will complete 5 of them. (If you complete more than 5, only the first 5 will be scored.)

For this assignment, create and complete your own practice exam:

  1. Choose 5 questions (from WeBWorK, textbook homework, or past tests) to become an expert on.
  2. Give yourself your 5-question exam to take in a setting as similar to the final exam setting as possible:
    • Set a timer for 75 minutes.
    • Put your phone on the other side of the room or in another room.
    • Use only your cheat sheet and a calculator.
    • Write clear, complete, and organized solutions.
  3. Share your question list and your full solutions as a post on the OpenLab.
    1. Title: Practice exam
    2. Category: Practice exam
  4. For one extra participation point: complete one of your classmates’ exams (don’t look at their solutions first!). Compare your solutions to theirs and post your full solutions in the comments. Include any errors you caught or suggestions for improving their work.

Withdrawing from class and “quiet quitting;” final exam absence

December 5, 2022 / / 3 Comments

Withdrawing officially and unofficially

The last day to withdraw officially from your CityTech classes is Wednesday, December 14.

Some of you are in a position where you would like to withdraw from the class but for some reason you cannot (for example, you will lose financial aid if you are not a full-time student or you are taking another course for which MAT 2680 is a co-requisite). If you do not intend to continue trying to pass this course but cannot drop it (“quiet quitting”) it is still important for you to come to the final exam and hand something in with your name on on. Failure to do so may result in a WU grade (instead of an F). A WU grade counts as an F on your transcript but can also jeopardize your financial aid, so please do attend the final exam.

Final exam absense

If you are absent from the final exam and need to take a make-up exam, you must submit your documentation to the Student Accessibility Center and, if eligible for a make-up exam, make official arrangements with the Math Department in N711. Scheduling a make-up exam costs $25; the make-up is usually given in January.
