See the weekly schedule below for more literature referenced in class.

Grading

The final grade is weighted as follows: Homework: 20%, Midterm: 30%, Final: 50%. Students who take both part I and II receive the same grade for part I and II according to the above scheme. For students who take only part I the final grade for part I is weighted 20% homework and 80% midterm.

Exams

There will be two exams, a midterm and a final. More details will be announced. Note that this class uses gradescope for grading exams, see here for more information.

Midterm Exam: Fri, Mar. 23, 14:15 - 15:30, East Hall 8

The exam begins at 14:15 sharp, so please come a few minutes earlier to be seated at 14:15. The midterm is about all material up to the Mar. 16 session. You only need to bring a pen, no calculators or notes! Please be aware of the University policy regarding missing exams: Policies for Undergraduate Studies. In particular, in case you are missing an exam due to illness (only with doctor's note) or an emergency, you have to notify me (by email) before the beginning of the exam!

Final Exam: Mon, May 28, 12:30 - 14:30, Lecture Hall Research I

The exam begins at 12:30 sharp, so please come a few minutes earlier to be seated at 12:30. The final exam is about all material from part I and part II of the course, with an emphasis on the material from part II. You only need to bring a pen, no calculators or notes! Please be aware of the University policy regarding missing exams: Policies for Undergraduate Studies. In particular, in case you are missing an exam due to illness (only with doctor's note) or an emergency, you have to notify me (by email) before the beginning of the exam!

Homework Sheets

Each week on Wednesday (except the first and exam weeks) there will be a homework assignment. These are an integral part of the coursework and working on the exercise sheets consistently is the best preparation for the exams. Note that

Homework Sheets are to be handed in individually at the beginning of class on Wednesdays. Alternatively, they can be deposited in a mailbox at the main entrance of Research I at some point before class on Monday (right next to the entrance there is a mailbox labeled "Foundations of Mathematical Physics"). No late hand ins except if you have been sick for several days during the time you had for working on the homework sheet (proved by doctor's note).
