Astro160 Grading PoliciesThere will be weekly problem sets, which will contain both quantitative problems and essay-type questions. Policies for lateness and collaboration on problem sets are described in this short essay on the theory and practice of problem sets. There will be two in-class tests (September 30 and October 28) and a final exam (December 11). You will be allowed to bring one piece of paper to the exam, filled with whatever information you choose. Calculators are allowed, but smart phones and devices with internet access are not. The discussion sections are required and will form a crucial part of the course: part of each section will be devoted to understanding the current problem set. There will be an optional 6-12 page paper.
There are a total of 600 points in the course, which will be determined as follows:

An optional paper, due at the end of the semester, will be worth 15% of the grade (90 points), and will reduce the weight of the weakest major portion of your grade from 30% to 15% (from 180 to 90 points). However, no problems sets or tests can be dropped altogether.
Students sometimes ask whether this course is graded "on a curve". This depends on what you mean by grading on a curve. I do not use the high-school grading scheme of 90-100%=A, 80-90%=B etc. Such a scheme essentially means that all good students should be able to answer all questions correctly, and that prevents asking interesting questions. So compared to traditional high-school grades, one might say the course has a curve. But I do not have fixed fractions in mind for how many students will get As, Bs etc. So students are not competing against each other; it does not hurt your grade to help someone else. Everyone who deserves an A will get one, regardless of how other students perform. In that sense, the course is not graded on a bell curve, or any other kind of curve.
The exact relationship between the numerical points given on the tests
and problem sets and the letter grades varies from year to year - this
is necessary because it can be hard to know in advance whether the
class will find a particular problem to be hard, or not. However, in
the past few years, the grading scheme has come out close to the
less than 50%: D or F
