This does not include the last homework grade, so I adjusted all grades
upwards. If you do not take the final, the grade shown here is your semester grade.
If you do take the final, the lowest midterm will be substituted by the final;
in that case the final is weighted to 300 pts, and the highest midterm to 200,
as was the initial class policy, and the total added to the homework (which
will include the actual last homework grade).
