Exam 3 this week

We have midterm Exam 3 this week, covering modules F, G and H.

Module I is ready but I will release the mini-quiz I after the exam.

Module H ready

This week's learning module H is now ready. Lot's of atomic and nuclear concepts!

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.

Go for Module G.

Sorry for not getting activated til this afternoon. It was a hectic spring break for me, but we are back on track. Learning Module G is now ready to tackle. The mini-quiz will be due on Friday this week, 5 PM, as usual. It has some simple yet nasty looking calculations, so study carefully.
