Grading and Goals 75% major assessments (chapter tests) 25% minor assessments (HW completion, graded OE questions, and do-nows) GOALS At least 50 students take the AP test. At least 8 students score a 5 No student scores a 1 At least 85% pass the exam (3 or higher) Average Score above 3.60 What is considered cheating? Looking at someone else’s test paper. (Classroom is full…no wandering eyes) Relaying information about tests to students in another block. Requesting test information from AP Stats alumni. Copying and sharing HW answers, (both nightly assignments and graded OE’s). What is not considered cheating? Working with one other person on a graded HW assignment…. as long as both students are actively involved in crafting the response. (Write your partner’s name on the paper). Looking up old AP questions online (apcentral.collegeboard.com) which resemble the one assigned. I value your integrity and hard work more than your test score. Expectations Your intention should be to take, and pass, the AP Exam. Disruptions caused by students (usually seniors) that decide not to take the exam will not be tolerated. You will study regularly outside of class, especially over spring break. Perfect attendance from now until May 9th.
