If you miss the midterm, you will get a mark of zero unless you have informed me BEFOREHAND and I have agreed that you may miss it.
If I agree that you may miss the midterm, there will be no make-up midterm. Instead, the weight of your final exam will be increased to include the weight of the midterm.
If you inform me AFTERWARD that you were unable to write the midterm, you will get a mark of zero.
