Missed it?
If you miss an exam or a homework deadline, don't worry! The system is flexible: You can miss two homework without consequences. Also, if you miss one midterm, your final will simply weigh more. Things happen - I understand. However, instead of giving make-up exams, I build in some flexibility in the grading scheme. So, you don't need to come and tell me what happened because there will be NO MAKE-UP AT ALL, under no circumstances, neither for homework, nor for the midterms, nor for the final exam.
