Format of Course

The course consists of 13 lessons and 2 exams. Each lesson consists of:

• A reading assignment from the text.
• A written assignment, from the text, to submit for grading and feedback.

Exams are mailed to a proctor selected by the student in accordance with Independent Learning's guidelines.

Grading

Score	Letter Grade
NOTE: The grading scale was revised on Nov 13, 2003. This grading scale applies to all students who complete the course after that date.
93-100	A
90-92	AB
83-89	B
80-82	BC
73-79	C
65-72	D
0-64	F

Each lesson and each exam is graded on a 100-point scale. The final score is computed as a weighted average, with the average of the lessons counting for 70%, and the average of the exams counting 30%. The exam average must be at least 40 for a passing grade. Assuming this is the case, the average of all your work is converted to a letter grade as shown in the table.
