Exams and Projects

Final:

A comprehensive final exam will be taken in class during Finals week. Time and date and topics TBD.

BONUS: Fellowship Application

An additional 10% of course grade (i.e., a full letter grade) is available to any student who writes a quality, submittable application for a major multi-year scholarship or fellowship (e.g. NASA FINESST, etc.). The application must be sent to Prof. Crossfield at least one week before the official submission deadline (so he can give you feedback to help improve it). Drafts for fellowships due after the last day of class must be turned in one week before the last lecture of class.
