By
looking at the relationships between the numbers of correct answers
and the time durations that students spend in taking tests, we
have found that there are typical patterns. The patterns of the
time durations spent in taking the test to each number of correct
answers depends on the difficulties of the questions. To easy problems
to solve, smart students use less time to solve the problems and
students with low academic ability need much time to solve. To
moderate problems to solve, every student requires the similar
time duration to solve the problems. To difficult problems to solve,
many students tend to use full time to the prespecified time duration,
but some students with low ability are reluctant to tackle the
problem.
