# EECS 280 Grade Calculator

Estimate your EECS 280 letter grade using scores from Canvas.

## Details

This section explains how each item is calculated in more detail.

### Lab

Enter the average of your lab scores after dropping the two lowest scores. Include an estimate of any future labs.

For example, if you received full credit on 8 labs and missed 3 (11 total) with 2 lab drops, you would enter 89%. There are 9 labs in the denominator after dropping two.

`LAB_SCORE = 100 * (8 * 10/10 + 1 * 0/10) / 9 = 89%`

### Entry Survey and Exit Survey

The survey scores on Canvas should be 100% if you received a confirmation email. Search your email for `EECS 280 Survey`

.

### Project

Calculate each project score as a percent of the total. Estimate any future project scores.

The project scores on scores on Canvas should match the Autograder.

### Exam

Enter the curved exam score seen on Canvas. Estimate any future curved exam scores.

The curved exam score on Canvas is calculated from the raw exam score on GradeScope.

Calculate your curved exam score using a Z-score. The max curved score is 100%.

`Z_SCORE = (RAW_SCORE - MEAN) / STDEV`

`CURVE_SCORE = CURVE_STDEV * Z_SCORE + CURVE_MEAN`

`FINAL_SCORE = max(RAW_SCORE, CURVE_SCORE)`

For example, let's say you scored 60% on an exam where mean=69% and stdev=17%. A typical curved mean and stdev are 81% and 9%, which makes the curved score 76%.

`Z_SCORE = (60% - 69%) / 17% = -0.529`

`CURVE_SCORE = 9% * -0.529 + 81% = 76.239%`

### Overall Percent

The Overall Percent is computed using the total weighted score table from the syllabus. The weights, which are the percentages in parenthesis (e.g., Lab 10%) should already match the syllabus.

The Total column in Canvas will *not match* the Overall Percent on the grade calculator until all assignments are added to Canvas at the end of the semester.

### Weighted Project Average and Weighted Exam Average

Compare the weighted project average and weighted exam average to the minimum scores thresholds from the syllabus.

### Final Grade

The Final Grade is computed using the calculated Overall Percent and letter grade table from the syllabus. The Final Grade includes the minimum scores thresholds.
