Multivariate Grade Calculator

About

The multivariate grade calculator aims to make it easy to evaluate numerous possible combinations in order to achieve a desired grade. The grade thermometer on the right shown in the demo displays the minimum and maximum possible final grade the user will achieve based on what they entered as well as their predicted final score.

The grading policy used in the demo is as follows:

50% — Three exams (all equally weighted)
40% — 10 programming assignments (all equally weighted)
10% — Mini-project

You can try using the multivariate grade calculator here.

The webpage was written completely from scratch with pure HTML, CSS and JavaScript without the use of any libraries or frameworks which regrettably resulted in many sloc. Most of the operations were done using JavaScript's LocalStorage. You may find the source code here.

An initial version was written in python using File I/O, NumPy and Matplotlib. You may find the source code here.

Part 1: Course information

For Part 1 - 3:
Using the same grading policy from the about section, assume that the following scores have been entered already.
Exam: 82%
Programming assignments (PAs): 80%, 84%, 65%, 70%

Under PAs information
Total assessments completed: 4 / 10

4 out of 10 total assignments have been done

Current standing: 299.00 / 400 = 74.75%

80 + 84 + 65 + 70 = 299
Average score so far is 74.75%

Final standing: 299.00 / 400 = 29.90%

Final average score if you do not turn in any more PAs

Overall percentage weighting: 40.00%

Percent weighting of PAs towards final grade

You had the opportunity to earn: 16.00%

With each PA being worth 4%, 4 were completed so far --> 4% * 4 = 16%

Secured percentage: 11.96%

With each PA being worth 4% --> 0.8*4 + 0.84*4 + 0.65*4 + 0.7*4 = 11.96%
The percent you gained towards your final grade

Permanent loss: 4.04%

16% (possibly earned) - 11.96% (earned) = 4.04%
The percent you lost so far

Part 2: Overall Grade Analysis

Under Overall Grade Analysis
Percent you had the opportunity to earn: 32.67%

4 programming assignments have been done worth 4 * 4% = 16%
1 exam done worth 16.67%

Total secured percent: 25.63%

11.96% earned from programming assignments
0.82 * 16.67% = 13.67% earned from exam

Total percent permanently lost: 7.04%

16% (possibly earned) - 11.96% (earned) = 4.04% from PAs
16.67% (possibly earned) - 13.67% (earned) = 3% from exam

Current progress and percentage: 78.45%

25.63% (earned) / 32.67% (possibly earned) = 78.45%

Highest possible final score: 92.96%

100% - 7.04% (total percent permanently lost) = 92.96%

Grade Thermometer:
MAX how much you can get if you get 100% on rest of work.
MIN how much you can get if you get 0% on the rest of work.

Remaining exams: 2 --> worth 2 * 16.67% = 33.33%
Remaining PAs: 6 --> worth 6 * 4% = 24%
Remaining Mini project: 1 --> worth 10%

Part 3: Sliders

Case 1:
The first student, Skye, is confident she can average 95% on the rest of the PAs and get full marks on the mini project. However, she is not confident about exams. Skye wants to aim for a B- in the class. Using the sliders, Skye finds that she will have to average 65% on the rest of the exams to earn a B- in the class.

According to chart, a weighted average of 80.75% required on rest of material
0.95 * 24% + 0.65 * 33.33% + 1.0 * 10% = 54.46%
54.46% (earned) / 67.33% (possibly earned) = 80.88%

Case 2:
The second student, Yoru, is confident on getting full marks on the rest of the PAs. Yoru is lazy and wants to skip the mini project. He is also aiming for a B- in the class. Yoru finds that he will need to average 92% on the rest of the exams to do so.

Case 3:
The third student, Reyna, is doing pass-fail and just wants a D-. Reyna is confident she will get full marks on the rest of the PAs and the mini project. She has several parties to attend and does not want to study for exams. Reyna finds that she will need to average 2% on the rest of exams to pass the class.

Deletion and Custom Cut-offs

Custom grade cut-offs can be entered as well as shown in the demonstration.
