Final and course grades
Final exam grades (with statistics) and final course grades have been entered into the gradebook. Thanks for a fun quarter!
CLUE final review session
CLUE will be running a review session for Math 307. It's on Sunday, from 810pm, in Mary Gates #234. It was suggested that you bring specific questions on specific problems.
I will also have my regular office hour on Monday, 11:30am.
Final Exam info
The final will be on Tuesday, June 5th, from 2:30  4:20pm, in the same room as class. You can have one doublesided handwritten sheet of notes, and you can bring the Laplace Transform handout. Scientific, but no graphing calculators.
The exam is cumulative, with a slightly bigger emphasis on Ch.6 material (Sections 6.1, 6.2, 6.3, 6.4). To the left you'll find two practice exams with solutions, and a handy guide to making your own study outline for the exam.
I'm not assigning any handin homework from 6.4, but you should know how to do initial value problems like Section 6.4 #110.
(optional) extra credit problem #3
This is due any time before the final exam, which is on June 5th. It's worth up to 6 points, added onto that exam (which is out of 100).

Your first homework is due Wednesday 3/28, but all you need to do for it is fill out the introduction survey below. Do this by 11pm on Wednesday. There are no written problems to turn in.
However, if it's been a while since you took calculus, you might want to check out the calculus review sheet below. You are expected to be 80% comfortable with that material (especially pages 1 and 3). Feel free to ask me about specific problems.
