Grading will be weighted as follows:

Item | Date | Weight |
---|---|---|

Problem Sets | 3/6 | |

Midterm | Th 12 Feb | 1/6 |

Midterm | Th 12 Mar | 1/6 |

Final | 3.30-6.30pm Sat 9 May | 2/6 |

If you add that up, it comes to 7/6. To make it add to 100%, I will delete the worst 1/6 of your score. That means you can do badly on 2 problem sets, or on 1 of the midterms, or your final will count only half.

The plan is to have 6 problem sets, roughly one every two weeks. The problem sets will be mostly mathematical.

There will be review sessions in class on Tue 10 Feb and Tue 10 March, the classes before the midterms.

CU's Fiske Planetarium has been reserved at the usual class time on the days in the following table. These shows are part of the course - exams may cover material presented in these shows.

Show | Date |
---|---|

Black Holes and Relativity | Tue 24 Feb |

The Milky Way | Th 19 Mar |

Galaxies | Th 2 Apr |

The Big Bang | Th 16 Apr |
