2. General scheme for doing homework

The steps below were written out in detail. This makes it look difficult, but each individual step is easy.

3. How to enter your answers

There are two question types:

4. Grading

The system allows multiple tries. If you don't get the correct answer on the first try, try again, and again and again. However random guessing is a waste of time, because of small penalties for incorrect answers. Some students dislike the penalties, but they create an important benefit for you: YOU DON'T HAVE TO WASTE YOUR TIME GUESSING.

Basic rules:

  1. Multiple tries are allowed.
  2. If, at any point, you have a good answer, enter it into the system.
  3. But random guessing is a waste of time. It will not improve your score -- you are just wearing out your mouse.

There are two types of questions, multiple choices and "numeric", where you type in your answer. Each type is graded differently.

4.1 Grading scheme for multiple choice questions

CAUTION: Some instructors set their classes to "one try". This section applies only if the system allows you multiple tries per question.

You can try any multiple-choice question multiple times. But random guessing is a waste of your time, because of small penalties for incorrect answers.

Grading is a "zero-sum game" where haphazard guessing will result in a score of zero. Thus, if you are unlucky on an individual question, you may get a negative score. These negative scores compensate for the positive scores which sometimes accrue from guessing, so guessers will average out to zero in the long run.
