Usually, exam time is imposed by the educational institution to facilitate examining a huge number of students within a limited time frame. While the instructors might consider the mid-level (both in knowledge and skills) students while preparing the exams, slower students might get overlooked. In this research, four midterm exams were used to study the effect of extended exam time on the students’ performance. The four exams were given to the students with a standard established time limit, and, in a different semester, were given to another group of students with extended time. The results proved that students generally performed better in the extended time exams with higher differences for mid-level students than for top and low level. It is recommended that instructors should consider the slower (in reading, writing and/or doing calculations) students while preparing their limited time exams.
