  • Students who received a score of 70% or below on Learning Target quizzes may re-take them to improve their score and to receive a passing grade showing that they understand the learning target. The cut-offs for re-takes are:
    • LT #4.1 - [mean, median, mode, range] - students who received a score of 6 or less (out of possible 9 pts.)
    • LT #4.2 - [simple & compound interest] - students who received a score of 7 or less (out of possible 10 pts.)

In order to do a re-take, students need to KEEP their old quiz, and BRING it in, with the correct answers (with explanations) on a SEPARATE FORM on the items they missed. [RETAKE FORMS AVAILABLE IN MR. USEM'S ROOM, or are available as a downloadable PDF document on his WEBPAGE] This will qualify them "ready to re-take" the quiz. Re-takes are to be done outside of regular class time, and can be done before-school, after-school, during recess, or during study-hall in Advisories on Thursdays. Students should make arrangements with Mr. Usem to do the re-takes. Students will have at least 2 weeks from when the quizzes are handed back to complete the re-take.

  • (Deadline for LT #4.1 & 4.2 is: Thursday, Jan 26)
