·       Midterm exam score adjustment formula

o   MT1_adjusted = MT1_raw;

o   MT2_adjusted = MT2_raw+12;

o   MT3_adjusted = MT3_raw+22;

The lowest of the adjusted scores will be dropped.


Example #1: if your raw scores are MT1_raw=93, MT2_raw=78, and MT3_raw=79, then your adjusted scores are MT1_adjusted=93, MT2_adjusted=90, and MT3_adjusted=101. Then MT2_adjusted score will be dropped. And the other two adjusted scores: MT1_adjusted=93. and MT3_adjusted=101 will be used toward your final letter grade. (Yes, even if the adjusted score is >100, the adjusted score(s) will still be used for your final grade.)

Example #2: if your raw scores are MT1_raw=61, MT2_raw=53, and MT3_raw=41, then your adjusted scores are MT1_adjusted=61, MT2_adjusted=65, and MT3_adjusted=63. Then MT1_adjusted score will be dropped. And the other two adjusted scores: MT2_adjusted=65. and MT3_adjusted=63 will be used toward your final letter grade.

 

Rationale: Since MT3 was harder than MT2 and MT2 was harder than MT1, we add 12 and 22 points to everybody’s MT2 and MT3 scores, respectively, to bring their averages to a similar level as MT1.  The midterm exam score drop policy will then be applied to the adjusted scores.

 

·        Format of the midterm exams

Both the format and content would be 95% similar to all the past midterm exams. 

Regarding the formula tables that will be provided in the final exam, they are identical to the ones provided in the past exams. Basically if you see a table provided in the past exams, you can expect the same table being provided in the current exam as well. Conversely, if a table/formula is NOT provided in the past exams, it will not be provided in the current exam either.

 

 

·       Missing a midterm exam

In this course, we automatically drop the score of the lowest of the three exams. As a result, if a student cannot attend a midterm exam, say due to unexpected medical reasons, the score of that midterm exam will be dropped.  The other two exam scores will then be automatically used for the final grade. The policy of “dropping the lowest midterm exam scores” is designed specifically to help students in this situation like medical emergency.  It is not designed to help improve students’ midterm exam scores, even though it may appear to have this unintended benefits.

 

          For those of you who still have questions about the rationale behind this policy, please continue reading the following examples.

          Example 1: Student A attended and completed all three midterm exams and got scores 75, 81, and 70.  Then his/her MT3 score will be dropped and the other two, 75 and 81 will be used for his/her letter grade.

          Example 2: Student B attended MT1 and MT3 but could not attend MT2 due to medical emergencies. His/her midterm scores are 77, ---, 73.  Then his/her MT2 score will be dropped and the other two, 77 and 73 will be used for his/her letter grade.

          Example 3: Student C did not have time to prepare for MT1 and MT2 and received 65 and 59, respectively. He/she would thus like to study extra hard for MT3.  His/her plan was that by getting a good grade for MT3, he/she can drop the lowest MT2 score.  By studying extra hard, he/she got 80 for MT3. As a result, his/her midterm exam scores are 65, 59, 80.  Then his/her MT2 score will be dropped and the other two, 65 and 80 will be used for his/her letter grade. Student C indeed harvested the score-improving benefits of this “drop-the-lowest-midterm-exam-score” policy.

 

Example 4: Student D also did not have time to prepare for MT1 and MT2 and received 62 and 63, respectively. He/she would thus also like to study extra hard for MT3.  However, on the eve before MT3, he/she got into a medical emergency and could not attend MT3.  As a result, his/her midterm exam scores are 62, 63, ---.  Then his/her MT3 score will be dropped and the other two, 62 and 63 will be used for his/her letter grade.

 

It turns out that many students have similar mentality as students C and D in Examples 3 and 4, respectively.  That is, their plan is to study extra hard in a later exam and hope that it will “make-up” for their earlier exam results. While this strategy sometimes works, see Student C, any student who chooses this strategy has to bear his/her own risk of having an unexpected medical emergency in the later exam, see Student D. It is not possible for the instructor to give a make-up exam for student D just because student C improves his/her score in this way. In a way it is similar to a situation that a student only studies 95% of the materials and hoping that all the exam questions come from that part.  While it is possible to gain a few extra points this way, the student has to bear the risk that the instructor may design a question out of the remaining 5% of the materials. It is a relatively small risk but it is a risk that student has to bear all by him/herself.

As a result, I would highly discourage any student to take the strategy of students C and D. Instead, the right strategy is to study as hard as possible for all your three exams.  In this way, you will receive similar scores of all three exams. It is true that there is no grade-improving benefit to be had but you also do not need to worry for the risk of having any medical emergency since you are well protected by the score-dropping policy.
