The below directions are what you will see in the real Exam 1 pdf
Directions to submit answers and shown work onto Canvas EX/QEX
To obtain credit for Exam 1, you need to complete the following:
• Enter your numerical answers and multiple choice answers (just as you have done with HWs) in the
“Exam 1” quiz on Canvas EX/QEX
• Submit 1 Single PDF of your shown work in the “Exam 1 (Upload Shown Work PDF Here)” quiz on
Canvas EX/QEX
Failure to submit a PDF file will result in a 0 exam score.
Directions to avoid penalization regarding rounding and units
To minimize penalization, you need to complete the following:
• Round your answers to 2 decimal places (e.g. 1.235V = 1.24V ). We understand several problem-parts
depend on answers from previous parts, so for these problems we have programmed Canvas to accept
a tolerance.
• Make sure the units used for your answers match what the problems ask for. The problems will always
state which units your answer must be reported with.
