Below the fold are the jokes from the final exam: enjoy!
I enjoyed having y’all in the class this fall: hope you guys had fun too. Feel free to stop by office to chat in the future if you want. Have a great holiday break!
(In arbitrary order)
I will submit the final letter grades on Saturday, so if you find any inaccuracies in any of your scores on UBLearns, please let me know by Friday. Unless there is a totaling mistake, we will not entertain any regrading requests on anything except the final exam and HW 10. Again all of these should be done by Friday.
Given all your scores (which you can find on UBLearns), here is how you can calculate your grade:
Your total score out of a can be computed by the following formula:
.
Check your score with the table below. (Just to be sure, I have also uploaded the score on UBLearns.)
Please don’t come to me and argue about the boundaries: in a few cases the boundaries are clear but in most cases, they had to drawn somewhere.
Have a good break!
The rest of the post is specific to grading.
The stats are as follows:
Below is the grading rubric that was used for the different questions. As usual these are general guidelines. Things might change slightly for specific cases.
There are two common approaches to solve Q3.The first one is greedy strategy by picking golds as large as possible.
The other one is that by expressing into a binary representation. Then, pick the corresponding gold weights in the binary representation of . For example, , binary representation is . So, you should include gold weights into your bag. For this approach, you should deal with two cases: and . For , you must include all gold bars. If you don’t deal with this case specifically, you will lose 5 points. For correctness of greedy strategy, you should use the property below
to prove your greedy strategy works. If you don’t do this, you will lose 3~4 points.
Mean: 47.34
Median: 65
Questions 1 and 2 were graded by me(Jiun-Jie) and question 3 was graded by Zihe. Any questions regarding the grading of a question should be directed at the appropriate TA. If there are any questions, you can come to our office hours, recitations, or email us.

Sorry for the goof-up: For those who submitted Q4 on HW 10, change you score accordingly!

Good luck on the exam and remember: do not panic!
You might notice that the answers are somewhat terse. I wanted to present “model” solutions, which would fetch you full points in the actual grading. Hope this helps!
