“The grade point average score among students choosing the Pass/Fail scale is somewhat higher compared to students who choose the A-F grading scale. Reduced stress associated with writing the degree project motivates those who choose the Pass/Fail grading scale. Enhanced motivation to do a good job on the thesis work and perceived good chances of receiving an A grade motivate students who choose the A-F grading scale.” (p.1993)
