Benchmarks for All Problem Solving Sets
Remember Problem Solving Sets count toward you grade twice! Once as a Lab and
once as a Homework
Minimum requirements that need to be met in order to receive this grade
You are responsible for using this rubric to determine the improvements necessary to receive a higher grade on you
next problem solving set. Areas of improvement will be designated by the numbers written next to your grade.
Grade
A
B
C
D
F
For example “B4” would indicate that the current grade would have been an
“A” if ALL numbers, not just MOST, had units following them. If you need
extra help/clarification please see Mr. Murray during office hours.
