# Engineering Probability Class 28 Thu 2019-04-25

Table of contents

## 1 Exam 3

Bring 3 2-sided crib sheets.

## 2 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.

## 3 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?
