IB 100 and 101 Fall 2009
First Exam Results
Biology 100 and 101 are different courses. The first
exam has a
different weight for the two courses. Because students in the two
courses have different experiences outside lecture, one might expect
the
median scores on the exam for the two courses to be different,
but in fact, the median scores in the two courses were very
similar on this exam.
The median score was 26.75/40 questions - about 5 points
lower than the
expected 80%
mark
(32/40). There were a few questions that some of you found to be
particularly challenging, so I have decided to adjust (curve) the
previously announced 90% (A), 80% (B), 70% (C), 60% (D) grade scale for
this exam by 4 questions on the exam. (See note below.)
In terms of number of exam
questions/40,
the scale is now:
A = 32-37/40 (21% of students in both IB 100 & 101)
B = 28-31/40 (22% of students in both IB 100 & 101)
C = 24-27/40 (35% of students in both IB 100 & 101)
D = 20-23/40 (14% of students in both IB 100 & 101)
F = <20/40 (8% of students in both IB 100 & 101)
Those of us on the course staff all want you to do
better on the next
exam and we will do our part to help you prepare. There are no
guarantees that there will be a "curve" for the next exam, so you will
need to work to improve as well.
If you did not do as well on this exam as you wanted,

your
grade on this exam will have on your course grade and see some
suggestions for improving your grade in the future. There are still
several opportunities to significantly improve your course grade.

(Note
about the "curve" - I will not add points to
anyone's score for this exam, but I will curve the course grade at the
end of the semester by a value proportionate to the value of 4
questions on this exam. This is the largest grade scale
adjustment I have ever made for these courses. There is usually
no curve necessary, or at most one or two questions.)
