If you qualify for membership, then your course grade will be computed in two ways. The first way is the usual way, counting everything, the second way disregarding Exam I, dividing by 400, and multiplying by 500.

Whatever is higher, is your final course score that would determine your grade, according to the scale:

450-500:A ;   420-449: B+ ;   390-419: B ;   360-389: C+ ;   315-359: C ;   270-314: D ;   0-269: F . No Curve!.

What do you need to do in order to join the Second Chance Club for Exam I?

• Don't write me Email asking me questions whose answers are clearly stated in this page.

• You scored at least 50 points on Exam I (in exceptional cases, people who scored less may also be eligible, but they have to contact me and get special permission)

• Make a copy of Exam 1, and for each thing that you got wrong, write a short explanation why it is wrong, and find five problems from the book of the same type and do them. For each "dumb" algebra mistake that you made, for example "simplifying" (quite a few people believed that r²-2r+2= (r-1)²) make up ten similar problems, of factorization, and solve them correctly. Also another "dumb" mistake was one student who "simplified" e^(t^2) *e^(t^2) as e^(t^4). Explain why this is wrong and make up similar problems.

  If you got the type wrong, explain why you were confused, and make up examples of the correct type.

• For each of the first ten lectures (i.e. those covered by Exam 1), pick two problems from the book, and do them.

• Put all the stuff in an envelope, with your NAME (printed, not cursive), and mark it "SCC I", and slide it under the door of my office, Hill 704, between 8:00am to 11:00pm on December 14, 2016.
