Flex 8-Week Courses

Chemistry B


Course Description

This .5 credit course discusses the systematic study of matter, its properties, composition, and changes.

Course Requirements

To earn credit for this course by the deadline, the following requirements must be met:

  • All mastery test modules must either be marked exempt or mastered
  • All modules without mastery tests must be completed, including pretests, posttests, semester tests, and drop box assignments

Time Requirements

This semester course contains 47 modules and is designed to fulfill the state-required 60 contact hours. Students should spend 7.5 hours per week, completing at least 6 module(s) each week of the 8-week program. Each bulleted item in the assignment list below is a module. TIP FOR SUCCESS: It is best to work on your course consistently to allocate time for technical and/or content assistance, if needed.

Grading Scale

An average of all scores on all modules will be calculated to determine a final grade. All modules are equally weighted. There are no + or – grades issued.

A = 90-100%
B = 80-89%
C = 70-79%
D = 60-69% (or 0-69% on post/end of semester tests)
I = Incomplete (course requirements have not been met)

Pretests

Pretests provide an opportunity to exempt out of modules within the unit based on prior knowledge; the pretests are not included in the final grade. You may take the pretest one time. While you are not required to master modules that have been marked exempt, the unit posttest or end of semester test may contain questions from these modules; therefore, you may choose to master these modules to prepare for the posttests. The grade for a module that has been marked exempt is 100% whether you master it or not.  Not all courses will have pretests.             

Mastery Tests

The minimum score required for each mastery test module is 80%. You may take the mastery tests multiple times. To unlock a mastery test, go back through the preceding activities for that module. You have unlimited attempts on the mastery tests, and each mastery test must be mastered or exempt in order to earn credit for the course. Review and retake each mastery test until you have earned at least 80%. The score for a module that has been marked exempt is 100%.

For any module that does not have a mastery test, all parts of the module must be completed.

Posttests/End of Semester Tests

The score for each posttest or end of semester test will be 0-100%. Each of these scores is factored into your final grade. You may take these tests one time. Not all courses have posttests or end of semester tests.
