CS360:
Systems Programming

Fall semester, 1997.
General Comments
This turned out to be a relatively easy test in that it was very
straightforward. It was probably the easiest test I've given in
CS360 in years. The way I anticipated the test going was:
- Question 1: All but the third part is note regurgitation, and
the third part requires tweaking the concept of part 2.
I looked at this as 7 free points, plus 3 easy points.
- Question 2: Part one was a giveaway. Part two required a little
thought, and part three required some good code reading ability.
12 is a great score. 10 is a good score. 6 is a reasonable score,
but anything below 10 means that you need to brush up on your
code reading.
- Question 3: I expected a lot of 10's and a few 12's. Below 10 means
you're missing something in your understanding of assembler.
- Question 4: This was an easy question. The hardest part was
having enough time to write the code, but if you just showed
me where and how the given code should be changed, you received full
credit. I expected lots of 14 and up scores.
In assigning grades, to this, I'd say that the following scale is
appropriate:
- 42.5-50: A.
- 40-42.5: B+
- 35-40: B
- 32.5-35: C+
- 27.5-32.5: C
- 20-27.5: D
- Below 20: F
