                                              Class meetings and sections: The class meets in Dwinelle 155 12-1 pm on Mondays, Wednesdays and Fridays. If you take this course you are expected to attend lectures, enroll in and attend one of the discussion sections listed below, do the homework each week, and take the two midterms and the final. All discussion sections meet MWF.

For detailed information about section numbers, room number and the name of the GSI consult the Math Dept web page, or go into schedule.berkeley.


Exams:

All the exams are "closed book". In particular you may not bring textbooks, notebooks or calculators.
No one should be too surprised if the problems in the midterms and/or the final are VERY SIMILAR to those in the homework. It follows that a good way to prepare for these exams is to attempt every problem in the homework assignment every single week. You will be motivated to do this in a way that is explained below.               

Exam Date Material covered
Midterm # 1    Sept 25, in class
Lay, Ch. 1-2-3-4
Midterm # 2    Nov 4, in class
Lay, Ch. 4-6
Final Exam    Dec 20 , 11.30-2.30pm
 Lay+NS&S


Grading:

 You will receive four grades, one for each of the following: homework and quizzes, the two midterms and the final exam. Homework and quizzes count 20%, the same for each midterm and the final counts for 40%. The overall grade is roughly based on a curve. Grades for exams or quizzes can only be changed if there is a clear error on the part of the grader, such as adding up marks incorrectly or forgetting to grade a question. The grade distribution for Math 54 in recent years was roughly as follows:  25% A,  35%B, 25%C and 15% D/F.
HOWEVER, I would be perfectly happy to give an A+ to everyone if they do deserve it. At the beginning of the class each one of you is starting at this mark. Just make sure that you work very hard and you will earn an A+.

VERY IMPORTANT

The final homework and quiz grade will be computed from the grades for the 30 best homeworks and 10 best quizzes. If you miss the first midterm the grade for the second midterm will count double. If you miss the second then the grade for the final will count for 60%. If you miss both midterms or the final, then you will fail the class. There will be no makeup exams or quizzes.

Homework and quizzes:

There will be a quiz given on a day decided by your GSI in the discussion sections.  Details on when homework is collected are left to your individual GSI.    There will be no make-up quizzes and late homework will not be accepted.  Collaboration on homework is allowed, but you need to write up your own.
The GSI for your section will pick 1-2 problems from each homework assignment and assign a "Pass/Fail" grade to these randomly chosen problems ( your GSI will give specific instructions for your section ). You have to attempt all problems and points will be taken out for problems that you do not try. This is my way of motivating you to really do all the problems. This will be useful when the midterms and the final exam come along. You should not be surprised is some of the problems in these tests are identical or very similar to some homework problems.

Following is the list of daily topics and homework assignments. The lectures do not cover all the course material, so you also need to read and understand the sections from the book. Reading ahead of the lectures should help a lot.
I cannot promise that I am going to cover all topics with the same level of detail. Reading the book CAREFULLY (there is no other way to read mathematics or science) is the only way to master this material. Another good way is to try to explain the material to your friends: only then you will realize that this is good for you too. I encourage people to form groups where you can try this sort of Socratic method.

Some words of advice:

The material in this class is, for most students taking 54, the bread and butter for many other classes to come later. The real physical/biological world is mostly governed by non-linear phenomena, and in this class we will ONLY cover an approximation to the real thing, namely linear equations and linear differential equations. We will cover many topics in a few weeks and the rhythm will be VERY DEMANDING. Some of you may find the first few weeks rather easy and may be tempted to drop the ball. BAD IDEA. A few lectures later you will find yourselves totally lost. Stay focused from day one, and make sure that you get a high mark in this class.
