In-Person Exams (Using the best 2 out of the three): 85 %
In-Person Quizzes and TopHat: 15 %
Exams are taken in-person in IO 102 (aka Innovation Hall Room 102).
The best two scores of the three exams are used (none are comprehensive).
Approximately 70 multiple choice questions. Study guides will be posted about a week before the exam.
Scantron sheets will be provided, bring an #2 pencil or HB lead (failure to use pencils will result in a zero).
Scores will be posted online to Canvas (exams are not returned to students).
Students need not take last exam, if they are satisfied with their scores on the first two exams.
Required in-person attendance in IO 102 (aka Innovation Hall Room 102) for one hour: 11 to noon.
Points are earned for both attendance and participation. To earn the TopHat participation points, your name must on the quiz. The quiz is handed out in the last 5 minutes. There are four multiple-choice questions related to the one-hour lecture (that you just sat through). Every student that takes the quiz earns the full points, there are no deductions for wrong answers. The quiz serves the purpose of recording your attendance and providing examples of exam questions.
Standard grading percentages are employed (70% and above is C, 80% and above is B, 90% and above is A)
There is (unadvertised) curving on the C range and to a lesser degree, some curving on the B and A ranges.
Syllabus (PDF). Take with a grain of salt, mostly a formality. This web page is your best source for information regarding the course.
Textbook purchase is totally optional.

Many thanks to Ryan Bertram (Astro A100 student), who introduced me to this neat YouTube video (courtesy of Rob Bryanton, Canadian author) that discusses the ten possible dimensions of our universe.
PhET's page that demonstrates elements of gravity.
Many thanks to Elizabeth Potter (Astro A105 student), who showed me this neat webpage highlighting the relative sizes from the Local Group down to Quarks (and the corresponding orders of magnitude, or powers of ten)
