More about Homework, Pre-Homework, and Pre-Tests.
1) Pre-HW scores serve two functions. First, students must score 50% or higher to unlock the related homework. Second, collectively they make up 4% of your grade. So, it's in your best interest to score over 50% on most of these assignments. I set it at 50% because I don't want the pre-homework keeping you from earning homework points.
2) By the end of the semester, there will be 60 to 70 homework/Pre-HW assignments. Your ten lowest Homework and Pre-HW scores will be dropped. So, not every score has to be perfect.
3) Homework assignments have due dates (which can be extended by 24 hours using a LatePass).
4) Pre-HW stay open all semester. Reviewing old Pre-HW assignments may be a good study strategy regardless of your original score. But, you can also raise a Pre-HW score from 50% up to a 100% at any time up to the day of the final without using any LatePasses.
5) Pre-Tests are NOT exact copies of the test. But at least 60% of the questions will be repeated (most likely with different numbers); the remaining 40% of the questions come from the same pool of possible questions (the pool of possible questions - or “test bank” - are the questions on the homework assignments).
6) Pre-Tests are NOT counted in your overall grade. So a low pre-test score is nothing to worry about.
7) It takes only ONE point on the pre-test to unlock the graded version of the test. I do it this way because I want the pre-test to be as stress-free as possible. You can take the pre-test up to four times. Feel free to take it early, take notes, and learn from your typos.
