07401/On the Term Test

Our Term Test will take place on February 28 at 6:20PM at Galbraith (GB) 120 on 35 St. George Street, across from the Bahen Centre for Information Technology. It will be two hours long and following it we will stay in class for some further discussion.
The material is everything covered in class until and including the class of February 14, 2007. Everything in the test be taken from our text book, and there will be two types of questions (or maybe sometimes the two types will be mixed within a single question):
 You may be asked to prove a theorem proven in class. The reason we prove theorems in class is that these proofs are important. Therefore I expect you to know them.
 You may be asked to solve exercises from the relevant chapters of the book, or minor variations thereof. These may be questions that were assigned as homework, but also, these may be questions that were not assigned before.
Office Hours. Dror will hold extended office hours on the week of the Term Test, on Monday from 2PM to 4PM and on Wednesday from 10:30AM to 12:30PM, both at or near Bahen 6178. Chao Li will hold his usual office hours, on Tuesday 12:002:00 at the Math Aid Centre, Sidney Smith 1071.
Preparing for the Test. Read, reread and rereread everything and solve lots of exercises from the book.
My (Dror's) system when I was an undergrad was to prepare a 23 page 50100 item list of points covered in class. I'd only summarize each point with one sentence, without giving any details and without trying to be precise, much like the list below that I prepared for the class of February 7. I would then go over my list again and again and again, crossing out every item for which I was sure I could complete all the details and supply all the proofs. I would only stop when there was nothing left to cross out.
