Grade estimate, halfway point

We are just past the midpoint for the semester, so it is a good point to help you estimate your grade status. If I were to give a mid-semester grade, it would be helpful, so that you know where you stand.
We cannot go by points yet, because there is another midterm, more points from mini-quizzes and the final exam still to come. That is normal.
However, we can go by percentage:

Letter grade estimate	Percentage
A	90% or higher
B	75%
C	60%
D	50%
F	less than 50%

As of 5 PM today, there will be 112 points officially on the books. So add up your exam 1, exam 2 and "points from mini-quiz" numbers, then divide that by 112. That quotient will give you your percentage as of 5 PM today.
Note: Some of you have already got your 4 points from mini-quiz G posted; the rest of you will have to wait until Saturday morning, but if you get that mini-quiz done and get at least one question correct, you can mentally pencil in 4 points for yourself from mini-quiz G.
