**Readings:**The readings are vital in the course.

There are 3 kinds of readings: ER chapters (18), ER appendices (18 not counting Appendix S), and Greene chapters (16 counting the chapter notes as part of the chapter and the preface as part of chapter 1).

- The mathematically-inclined reader that Greene keeps addressing in the notes is you.

Each of the kinds is worth 5 % of the total grade for a total of 15 % of the total grade.

Students report to the instructor (preferably by email) when you have completed a reading and 1 point will be assigned for each reading: there 18, 18, and 16 points, respectively, for the ER chapters, ER appendices, and Greene chapters.

In the Tentative Schedule below, a schedule is given for the readings.

It is strongly urged that the students keep up to this schedule.

- Cold feet are setting in already before day 1. If the going gets way tough, we may cut out some chapters or chapter sections. I'll indicate such cuts on the Tentative Schedule below.

But on the other hand, you'd really like to have had brush with all this stuff in the years to come.

Try to grind out 10 pages a day.

**NOT**going to lecture on everything covered in the readings.

Maybe not even half.

The style of the lecturing will be to skip stuff readings cover and is easy to understand and needs no instructor explication---this means readings have to be done and as much in advance as possible.

- The instructor will also skip when he's clueless---well you know what they say: when the going gets tough, it's time to bug out.

You should also be warned that instructors and books can both propagate misconceptions---a part of everyone's scientific life is clearing up misconceptions they acquired long ago from some formerly ``revered'' authority.

Some ER chapters, most ER appendices, and all of Greene are **NOT** going to be lectured on.

Naturally, what is not lectured on is going to less weighted in exams---I do try play fair.

**Homeworks:**There will be 15 homeworks as specified in the Tentative Schedule below.

There is one for each of the fiducial lectures of the course.

The homeworks are **NOT** handed in.

But they are counted: 1 point for each: so 15 points in total.

The students report when they have completed homeworks (preferably by email) and their points will be assigned.

After the homework is completed, students are free to look at the posted solutions.

Homeworks count for 5 % of the total grade.

It is strongly urged that students keep up to the schedule on the homeworks.

Typically about 50 to 70 % or more of the exam questions will be drawn from the homeworks or, in the case of the **FINAL**, past exams also.

Questions that reappear on the exams might be tweeked a bit from previous versions.

New questions on exams will be similar to the homework questions.

Some will be challenging.

**Exams:**There will be 2 in-class exams and a 2-hour

**COMPREHENSIVE FINAL**.

The in-class exams cover the material up to some cut-off point that will be announced in class and on the course web in the Tentative Schedule .

The in-class tests are each worth 20 % of the total grade for a total of 40 % of the total grade.

The final is worth 40 % of the total grade.

The tentative dates for the exams are:

_________________________________________________________________ Exam Date Solutions (posted post-exam) _________________________________________________________________ Exam 1 Feb25 M Exam 1 solutions Exam 2 Apr25 F Exam 2 solutions Final Exam May07 W Final Exam solutions The final is at 7:30--9:30 am---not my call---in the regular class room as specified by Final exam schedule for 2008 Spring. _________________________________________________________________The in-class exams will consist of multiple-choice questions and a few full-answer questions that will be mostly mathematical.

The final will be like a double-class exam in terms of questions of various kinds.

The exams are closed-book.

- An equation sheet will be provided: it's the same equation sheet that comes with the homeworks.

Cell phones **MUST** be turned off and be out of sight.

There are **NO** scheduled review days, but the instructor may review some mathematical problems on request: remember the solutions to homework problems will be posted.

Make-up exams are possible, but students must ask for them promptly and avoid knowing anything about given exams.

**Evaluation and Grading:**The 6 grading categories, their weightings, and their drops are: ER chapter readings 5 % no drops ER appendix readings 5 % no drops Greene readings 5 % no drops homeworks 5 % 1 drop 2 in-class exams 40 % no drop 1 comprehensive final 40 % no drop Each in-class exam is worth 20 % of the final grade.

Attendance is **NOT** kept and **NO** marks are assigned for attendance.

Students are encouraged to keep good attendance.

There are absolutely **NO** extra credits.

Letter grades will be assigned following the UI catalog---which allow instructors some freedom of interpretation.

The instructor uses a curve to automatically assign letter grades during the semester. There is no fixed scale.

The final grades are decided on by the instructor directly.

Students can always ask the instructor for their current mark record and letter grades. Queries by email are probably best for this.

The instructor will submit midterm grades and final grades as scheduled in the academic calendar.

Remember that after an instructor has submitted final grades, any adjustment (except for purely clerical error) is extremely difficult. Students should make any queries about their final grades before the instructor submits them.

Beware of aliens bearing grades.
