Problem & Question Session: Th 5-6 in EMS D258 (Rob Coe)

Required Textbook: C.M.R. Fowler “The Solid Earth” Cambridge 2005, second edition.

Note: This is a widely acclaimed prize-winning text that you need to have for this class.

Grading: Lab 35%, Problems 20%, Midterm 15%, Final (covers whole quarter) 30%

Note: There is only one grade for this course. Because lab and lecture materials are inseparably intertwined,

the lab scores are averaged in with the other scores and there is only a single grade and evaluation for 110C and 110N.

Dates: Lab writeups are due at the next week’s lab section.

Problem solutions are generally due on the following week at Thursday lecture.

The midterm exam is Thursday April 28.

The final exam is Tuesday June 7 from 4-7 pm.*

*Note corrected final exam date and time, compared to the syllabus handed out the first day!
