Protractor use

Protractor practice quizzes

  1. A practice version on paper will be handed out in class on Friday, April 19, 2024. This is what your real quiz will look like. We will do the real quiz sometime after we return from Spring Break.
  2. Three practice quizzes and one Brooklyn special practice quiz. Do at least one, but really you should do enough so that you feel confident you will get a good score on the one that gives you homework credit.
  3. A single practice quiz for real homework credit. This is not optional. You must finish it before 8:00 AM, Thursday, May 2, 2024.
