# Econ 3012: Intermediate Microeconomics

Course description

Office hours:

Kirill Evdokimov:

Problem sets and exams:

There will be 6 problem sets, a midterm exam, and a final exam. The midterm exam will take place on October 9. There will be a review session on October 7. The final will take place on Saturday, December 7 for the 9:05 - 9:55 MWF Section, and Monday, December 14 for the 10:10 - 11:00 MWF Section. The final will be cumulative, although it will likely emphasize the material from the second part of the course.

Grading:

Problem sets and exams will not be graded on a curve. The course grade will be determined by the following weights: 20% problem sets, 30% midterm, and 50% final. I will curve the course grade.

Textbook

The official textbook is Intermediate Microeconomics: A Modern Approach by Hal Varian. However, I will not be following the textbook closely. I will be providing my own notes and problem sets. The textbook is a good resource for additional problems and examples, but it is not required.
