Grading Policy

Your grade for this course will be calculated out of 300 points. The minimum score required to pass and become eligible for college credit for this course is 210 points, or an overall course grade of 70%. The table below shows the assignments you must complete and how they'll be incorporated into the overall grade.

Quizzes

Quizzes are meant to test your comprehension of each lesson as you progress through the course. Here's a breakdown of how you will be graded on quizzes and how they'll factor into your final score:

• You will have 3 attempts to take each quiz for a score.
• The highest score of your first 3 attempts will be recorded as your score for each quiz.
• When you've completed the course, the highest scores from your first 3 attempts at each quiz will be averaged together and weighed against the total possible points for quizzes. For instance, if your average quiz score is 85%, you'll receive 85 out of 100 possible points for quizzes.
• After your initial 3 attempts, you can take a quiz for practice as many times as you'd like.
• You will need to pass each quiz with a score of at least 80% to earn course progress for the lesson. However, it is not necessary to earn 80% within the first three quiz attempts.

Assignments

Assignments are intended to assess your application, analysis, and critical thinking skills in relation to the concepts you learn in the course. Two assignments are required for this course. You can access them here.

• All assignment scores will total up to 100 points.
• Your assignment(s) will be graded by a Study.com instructor.
• The instructor will provide a graded rubric for you along with feedback on what you did well and what could be improved.
• If you are unsatisfied with your score, you will be able to revise and resubmit your assignment(s) twice. You are free to resubmit an assignment within two weeks of your most recent exam attempt or at any point if you have an active college accelerator membership.

Proctored Final Exam

The proctored final exam is a cumulative test designed to ensure that you've mastered the material in the course.

• You'll earn points equivalent to the percentage grade you receive on your proctored final. (So if you earn 90% on the final, that's 90 points toward your final grade.)
