Welcome back from Spring Break.
Test #2 runs through the week of March 13-17. I advise you to take the test by Thursday if indications are that crowds are expected at the testing centers. Do remember you can check on wait times as the week progresses. Information about wait times is always available as was explained in a post dated February 7.
Test #2 covers Parts 3 and 4 of the course, i.e. the simplex method for solving linear programming topics and counting techniques to be used later in our study of probability.
