Here's how you did on the final exam.

Q 1-4. Most people got the right answers.

Q 5. 34 got it right (#2), but 22 got it wrong. The wrong answers were pretty spread out, with #1 the favored choice of wrong answers.

Q 6. Most got it right (#3) but 25 had wrong answers. The most popular wrong answer was (#2)

Q 7. Most got it right (#3)

Q 8. 28 were right (#5). But 28 were wrong. The most popular wrong answer was #1.

Q 9. 30 were right (#1). The most popular wrong answer was #4. This question had a typo, but only one person asked about it, and that was after most of you had left. I assume most of you read it as intended.

Q 10. Almost everyone got this right (#2)

Q 11. 23 right (#3). The least popular wrong answer was (#2). The others were evenly split.

Q 12. Most had this right (#1)

Q 13. 37 right answers (#1). No strong favorite wrong answer. 

Q 14. Most had this right (#3).

Q 15. Only 12 got it right (#4). Each of the wrong answers was selected many times.

Q 16-27. Most people got these right.

Q 28. Many of you tried to use the extension to the Master Method. 

Q 29. 30 were right (#2). (!3) and (#3) were popular wrong answers.

Q 30. 38 got this right (#3).

Q 31. 32 got this right (#1), but 24 got this wrong. You all should have known this!

Q 32. 20 got this right (#3). The favored wrong answer was (#4). 

Q 33. 31 got this right (#4). The most selected wrong answer was (#3).

Q 34. 23 got this right (#2).  A significant number of people in the afternoon section selected (#1). A significant number of people in the morning section selected (#4), is the same answer but more confusingly. Both answers say that there is no effect, which is wrong.

Q 35. 29 got this right (#2). The favored wrong answer was (#3).

Q 36. Almost everyone got this right.

Q 37. Only 17 got this right (#1). The favorite answer was (#3).

Q 38. 21 got this right (#4). None of the other answers have anything to do with topological sorting.

Q 39 - 49. Most people got these right.

Q 50. 32 got this one right (#4), but a disappointingly large number of people picked (#3), which has nothing to do with Bloom filters. In fact none of the other answers make any sense in the context of Bloom filters. That suggests that there is a significant gap in understanding the material and that many of the correctly answered questions were done by rote rather than understanding. There was a lot of cramming this past weekend. It probably helped some of you get higher scores, but it may not have helped you deepen your understanding.

Sorry. The questions should be visible now.
