Re-create the calculation of your grade!!

The grading scale is: 90% and above = A; 80-89% = B; 70-79% = C; 60-69% = D; 59% and lower = F

You can figure out what you need on the final to get a certain grade - go to the bottom of the page...

First, you should get your slip of paper with all of your grades on it.


Attendence and Reading Quizzes
This is worth 10% of your grade so I calculated how much of that 10% you actually earned
Take the number of days you attended and divide that by the number of days possible to attend (same goes for the quizzes)
Add together the attendence and quizzes then divide by 2 (we're taking the average) then multiply by the percentage (remember that 10% = 0.10)

The formula is: ((ATT/#days + RQ/#quizzes)/2) x 0.10

An example: JimBob attended 20 out of 25 days and submitted quizzes for 24 of the 25 -- ((20/25 + 24/25)/2) x 0.10 = 0.088 = 8.8% of the 10% possible

Labs
Worth 25% of your grade
140 points were possible. The number of points listed is what I was given by your TA.

The formula is: ((#points/140) x 0.25

An example: JimBob earned 130 points out of the possible 140 -- (130/140) x 0.25 = 0.232 = 23.2% of the possible 25%

Assignments, etc.
All of the assignments are worth 15% of your grade
Many assignments were worth differing numbers of points, so they have to be averaged separately (this version obviously doesn't include the portfolio)

The formula is: ((Supp1/10 + Asgn1/20 + Sup2/10 + Asgn2/20 + Asgn3/20 + Asgn4/25)/6) x 0.15

An example: JimBob earned 9, 20, 0, 18, 18, 22 on his assignments -- ((9/10 + 20/20 + 0/10 + 18/20 + 18/20 + 22/25)/6) x 0.15 = 0.115 = 11.5% of the possible 15%

Tests
The best 3 of 4 tests is worth 30% of your grade
For each test, 1 multiple choice question was worth 2 points, then the written stuff had the number of points possible labeled (either 2, 3, 4 or 10)
Each test had a certain number of points added to everyone's score: Test 1 +15, Test 2 +15, Test 3 +10, Test 4 +15
The grade that I considered was the one that had points added to it and that is the one you see on your sheet.

The formula is: ((TestX/100 + TestY/100 + TestZ/100)/3) x 0.30

An example: JimBob got 65, 78, 91, and 75 on his 4 tests, the 65 gets dropped -- ((78/100 + 91/100 + 75/100)/3) x 0.30 = 0.244 = 24.4% of the possible 30%

Total Percentage Grade
I just added up the various percentages to get what you have out of the possible (excluding the final and the portfolio)
Our example: JimBob has 8.8%, 23.2%, 11.5% and 24.4% -- (8.8 + 23.2 + 11.5 + 24.4) = 67.9% out of the possible 80% (10 + 15 + 25 + 30)
Therefore, JimBob currently has 84.9% in the class (67.9/80 = 0.849 = 84.9%) which is a B


Bonus points
Bonus points go along with your tests and are factored into that grade and then the totals are re-added (a little more complicated)

The formula is: {%attend + %labs + %asgn + [(%tests/0.30*3 + bonus)/3/100*0.30]}

An example: JimBob got 25 bonus points -- {8.8 + 23.2 + 11.5 + [(24.4/0.30*3 + 25)/3*0.30]} = 70.4% of the possible 80%
Therefore, JimBob has, with bonus points, 88% in the class, which is still a B

The Portfolio
Just add it in to the Assignments, etc. grade (make sure to divide by 7, not 6)

The formula will be: ((Supp1/10 + Asgn1/20 + Sup2/10 + Asgn2/20 + Asgn3/20 + Asgn4/25 + Portf/30)/6) x 0.15

An example: JimBob got 27 on his -- ((9/10 + 20/20 + 0/10 + 18/20 + 18/20 + 22/25 + 27/30)/7) x 0.15 = 0.117 = 11.7% of the total possible 15%

The Final
It is worth 20% of your total grade; it cannot be dropped

The formula is: (score/200) x 0.20

An example: JimBob got 175 out of the 200 points -- (175/200) x 0.20 = 0.175 = 17.5% of the possible 20%

Therefore, JimBob, in the entire course, got (8.8 + 23.2 + 11.7 + 24.4 + 17.5) = 85.6% out of the possible 100%
With the bonus points, he got {8.8 + 23.2 + 11.7 + [(24.4/0.30*3 + 25)/3*0.30] + 17.5} = 88.1% out of the possible 100%


And that is how you calculate your grade :)
I know it's a mess, but if you want to know, here it is...



What you need to get on the final...
First of all, you have a calculation in front of you already done by me (on your slip of paper) - your percentage score up to right now is on that paper. The maximum possible you can get if you don't take the final at all is 80%, which is a B. If you are happy with a B, you don't have to take the final at all. Most people currently have lower than 80%, so they may want to take the final.
Let's say you think you will get 100% on the final -- that means you will get all 20% of the possible 20%. Add that to the percentage on your piece of paper. That will be your percentage. Otherwise, you may want to look at the example...

An example: Let's say you are in JimBob's shoes - he currently has 67.9% in the class (no bonus). If he aces the final, he can get an 87.9% (a B) in the class (67.9 + 20 = 87.9). With his bonus points, he can get 90.4% (an A) in the class.


How can you use this?
First, figure out what grade you WANT to get.
Subtract your current percentage (with bonus I guess) from the percentage you WANT. If your result is greater than 20, you need to try for a lower grade.
Take your result and convert it into points on the final [((result/20) x 200) = #points on final]. That number is the number to shoot for :)

Remember, this only works if you keep the same average grade for your assignments (remember you have a portfolio due!!)
