Course Evaluation: The final grade will be based on the following three components:
1) Final exam: The final exam will count towards 40% of the final grade.
2) Homework: There will be four homework assignments throughout the semester and they will count towards 40% of the final grade.
3) Class performance: The students will be required to make short (~30-45 min) in-class presentations approximately once every two weeks on pre-specified topics. These will count towards 20% of the final grade.
