Many students had a hard time with 5 (c) and (d).
The points breakdown was as follows:
Problem 1: 5 pts = (a) -> 2 + (b) -> 3
Problem 2: 20 pts = (a), (b), (c) and (d) 5 each
Problem 3: 5 pts = (a) -> 3 + (b) -> 2
Problem 4: 5 pts = (a) -> 2 + (b) -> 1 + (c) -> 2
Problem 5: 10 pts = (a) -> 2 + (b) -> 3 + (c) -> 2 + (d) -> 3
As usual, if you have issues with how this homework was graded, please
write down on a sheet paper your score, what you think your score should
have been, and your reason why. Attach this to your assignment and return
it to us in quiz section tomorrow or in class on Friday.
In particular, one student told me that he expected all of the problems on
the homework to be weighted equally and chose how to spend his time
accordingly. We chose to put more weight on some problems (see the point
distribution above) because we thought these problems took more work and
deserved a greater weight. If you feel you were hurt by this policy, you
may recompute your score so that all problems are out of 5 points (i.e.,
divide your score on problem 2 by 4 and your score on problem 5 by 2).
If this improves your percentage on the homework, submit to us for
regrading.
Note that Homework 3 has an explicit point distribution, as will the
final, so this problem won't arise again.
Cheers,
Janet
