Quizzes/Homework/Class Participation   25% of grade
Lab Assignments                        25% of grade
Final Exam                             20% of grade
TOTAL                                 100%

90% +		= A
80 - 89 %	= B
70 - 79 %	= C
60 - 69 % 	= D
Below 60 %	= F

Caveats:

1. Safety Glasses: Safety glasses with side shields are required to be worn during lab activities associated with this course. This requirement complies with accepted eye protection practices and Kansas State Law (K.S.A. 72-5207). Safety glasses must meet American National Standards Institute Z87.1 specifications. Safety glasses brought to lab and worn will be part of the lab grade. Failure to bring safety glasses to lab will result in the students being dismissed from class until they have safety glasses.
2. Note: Most prescription eyewear does not meet ANSI Z87.1. Students who wear prescription glasses must: 1) provide evidence that existing eyewear meets ANSI Z87.1, or 2) wear cover goggles (if allowable), or 3) purchase and wear ANSI Z87.1 prescription eyewear.

Disabilities:

If you are a student with a disability, and if you will be requesting accommodations, it is your responsibility to contact Access Services. Access Services will recommend any appropriate accommodations to your professor and his/her director. The professor and director will identify for you which accommodations will be arranged.

JCCC provides a range of services to allow persons with disabilities to participate in educational programs and activities. If you desire support services, contact the office of Access Services for Students With Disabilities (913) 469-8500, ext. 3521 or TDD (913) 469-3885. The Access Services office is located in the Success Center on the second floor of the Student Center.
