Future faculty users could allow students to play at individually chosen times. The students are free to define their own strategy which "easy", "medium" and "hard" . We expect that further applications and some improvements of the test will lead both coefficients to increase toward more desirable values of 0.85 or 0.9, respectively, which would make the reliability "very good" or "excellent". Normality tests for each question showed that skewness and kurtosis of 30 questions is within the recommended range, given α = 0.01, so the critical z value is ±2.58 . Questions 7, 15, 21, 23, 26 and 30 do not satisfy these criteria, but are close. Within the five categories, each category had only one question not satisfying the above criteria, except the "atomic structure and chemical bonds", which had two such questions. Nonetheless, the values of Hake's gain and other results in this report have included these questions, since their impact on increase or decrease on the gain is much smaller than the uncertainty.
