math 2210 is hard

These percentages are based on the grades of the 58 brave calcunauts who took the fourth exam and, also, took calculus 2 at UW. The vast majority of calcunauts who earned an A or B in calculus 2 passed calculus 3 with an A or B. But it seems calcunauts who earned a C in calculus 2 have a high risk of not passing.

Of those passing Math 2205 with an A, 75% received an A and 25% received a B (100% passed).

Of those passing Math 2205 with a B, 12% received an A, 48% a B, and 32% a C (92% passed).

Of those passing Math 2205 with a C, 0% received an A, 0% a B, and 61.5% a C (only 61.5% passed).

course grades

Of the original 84 brave calcunauts who registered with WebAssign in January only 66 (79%) took the final exam. This histogram shows overall scores for those remaining calcunauts; each large rectangle represents 3 calcunauts. Enjoy the summer.

exam 4 post mortem

Scores ranged all the way from 97 down to 3. For this histogram I deleted exam scores lower than 30. Each full size block represents 2 calcunauts. These scores are in WebAssign now but we haven't decided on grade boundaries yet. If your final score is right below one of the cutoffs, your course grade might end up higher. Stand by.


exam status

I think the exams will be ready for you to pick up today, but not until after 2:30.

solutions to exam 4

Aaron S. and Will R. found mistakes in my solutions to 9 and 10. I updated the solutions. All hail Aaron and Will!

As you can see from the graph last semester's exam 4 was pretty difficult. I hope my solutions are correct; let me know if you see any sketchy bits.
