If you wish to take the exam of a section for which you are not officially registered, you may do so provided that you have cleared it with

Ground Rules for Tests
Books and notes are excluded from tests and examinations, except that you may bring one page of notes (i.e., one sheet of 8.5"x11" paper, written on either or both sides) to each of the tests, and at most two such pages to the final.
Requests for changes in midterm-test grades must be submitted to the instructor in writing within one week after the test papers are handed back. Delay in picking up a graded test paper does not extend this deadline.
The university requires the final course grade to be expressed as one of the letters ABCDF. In translating numerical averages to letter grades, I observe the traditional correspondences, i.e., 90 ~ A, 80 ~ B, etc., except that the letter-grade thresholds may be lowered (never raised).
This means that, for example, a course average of 80 is guaranteed to earn a B, even if it's the lowest average in the class.
Semester scores are computed using the following formula (all scores are expressed as percentages):
s = 0.1 * h + 0.25 * (sum[m1', m2', m3'] - min[m1', m2', m3']) + 0.4 * f where
s = semester score
h = homework average
m1', m2', m3' = adjusted midterm-exam scores
f = final-exam score
Adjustment of exam scores
When the averages of the three midterm exams differ significantly (as they often do), a student who misses a high-average exam is at a disadvantage relative to a student who misses a low-average exam.
To minimize this effect, the midterm-exam scores used in computing semester averages are adjusted. The adjustment puts the three exams on an equal footing, by adjusting the scores of the exams so that all three midterms have the same average score.
For a below-average midterm, a score of 100% gets no adjustment, and an average score gets an adjustment equal to the difference between the test's average and the three-midterm average. Those two points determine a straight line, which in turn determines the adjustment for all other scores.
For an above-average midterm, a score of zero gets no adjustment, and an average score gets an adjustment equal to the difference between the test's average and the three-midterm average. Those two points determine a straight line, which in turn determines the adjustment for all other scores.
A similar adjustment is applied to final-exam scores, to minimize the effects of differences between the averages of the two sections' final exams.
The adjustments use the following formulas (all scores are expressed as percentages)
For an upward adjustment:
m' = m + (a' - a) * (100 - m) / (100 - a) where
m' = adjusted score
m = original score
a' = adjusted average
a = original average
For a downward adjustment:
m' = m + (a' - a) * m / a where
m' = adjusted score
m = original score
a' = adjusted average
a = original average
