Exam 3
------

Bring 3 2-sided crib sheets.

Grade to date
-------------

Lingyu computed piazza and iclicker grades.

For iclickers:

#. They were used in 13 classes.
#. You got 1 point for each class that you used your iclicker.
#. Multiply the total by 10/13.
   
For piazza:

#. For each of 3 months, 1 point per contribution, up to 2 points.
#. Then multiply by 10/6.

I computed a percent grade to date.

I uploaded it in column **Tot1** to LMS.

It cannot fall, but may rise, because:

#. You got knowitall points.   I haven't yet included them.

#. Your homework 11 grade is higher than your lowest grade from hw1-10.

#. You write exam 3 and it helps.

If the class wishes, I can lower the weight of the piazza grade from 10% to 5%, and scale everything else up.   Do you wish?

The letter grades will be at least as generous as the syllabus shows.   I may lower the cutoffs.

I believe my courses to have higher GPAs than average.

Piazza and iclicker
-------------------

They're a mess to compute.

I use them because I believe them to be pedagogically good.

However what do you, the class, think?
