Get ready for the fourth test and final review test!
Finish and Review Fourth Section; Class
Review will be later in the week.
Final Exam: Group
4, Saturday May 13, 8-11am
(Your lucky day! You should not take this class if you know you can't make this
final.)
3 Midterms: 13% each
(Fri. Feb. 10, Wed. Mar. 8, Wed. Apr. 12)
Final: 25% (1/2 review) (May 13)
Section: 36% (5% attendance, 5%
participation, 6% labs and projects, 20% homeworks)
Exams are objective (T/F, multiple choice). You are allowed to use a "cheat sheet" (this course is about comprehension, not memory). We will also tell you the subject of all exam questions ahead of time (but not the exact questions, of course). Most of the minimal math in this course will be on the homeworks and labs, very little on the exams. Simple algebra is all you need to know. Labs require you to actually look at the sky at night, and to take reasonably careful observations and notes. There will be several options for these. You can also show us what your talent is with other projects. Some homework/exam score replacement will be allowed for writing, research, art, or other projects that are germaine and have effort in them. GSI approval for these must be obtained before starting.
If you are taking the course only because you have to, we strongly encourage you to consider taking it P/NP. Students taking it P/NP will not have to do all the homeworks or exams. That is, a section of each will be set forth so that if you score 80% on it, you don't have to do more. It may well be in your interest to do more, of course. These sections will be more about "book learning" and less about "stretch thinking". Those taking it for a grade must do all the material, and will have to understand the material on a somewhat deeper level.
This course is not one in which cramming is very useful if you haven't kept up. We will offer a special homework session each time one is due (most weeks). "The Astronomy Learning Center" (TALC) is a good place to do homework with friends, and GSI's will be around to help. We don't want you to struggle, and we promise you will be amazed by what you learn about!
Extra credit projects will be offered, but not lots (this is only useful for moving grades if you are close anyway).
