I am going to calculate what the imaginary student, Suzie Que, must do to make the grade she seeks in this course.

To see what you must do, just follow the calculation, but use your grades in place of Suzie Que’s.

How to Calculate Your Grade

First I am going to determine how many bonus points Suzie will get.

Remember there are more than enough pop quizzes to get a maximum of 40 bonus points.

I am going to assume that Suzie’s pop quizzes gets her 35 points.

Next I need to estimate what Suzie’s lab

experiment average will be at the end of

the semester.

I estimate that to be 97.

So far she has 97+35=132 points.

Now I must add in her two lecture exams so far.

For example, let’s assume Suzie got 31 correct on the first test and 36 correct on the second. (Each test had 50 questions.)

Let’s see how many points that gets her.

36x150=108

50

Her total is now 93+108+132=333.

31x150=93

50

Let’s assume that she wants to make a “B.”

That requires 640 (actually 630) total points.

630-333=297

297 points on the remaining exams is

required to make a “B.”

There is still 400 points available on the

remaining exams (this includes the lab

final).297

x100=74.3400

In this example Suzie can make a middle “C” (74.3%) average on the next two exams and lab final and get a “B” in the course.

Please note that in this example Suzie’s best test score on the first two lecture exams was 36.

This gives her a % grade of

36x100=72

50

Thus you can see that Suzie still has a chance for a “B” in the course even though she made a low “D” and a low “C,” respectively, on the first two lecture exams.
