Overall Percent

Your overall percent is the weighted average of percent scores on each assignment, according to the weights given in the syllabus and shown in parentheses above, e.g. "Labs (5%)".

Minimum Score Thresholds

Your weighted project average and weighted exam average must meet the minimum pass thresholds given in the syllabus in order to earn a C or better. Otherwise, the highest final grade you may earn is C-.

Your final grade is determined according to the letter grade table from the syllabus, subject to the minimum pass thresholds.

Each exam is curved to account for variation in difficulty. See details below. Nothing else is curved. Final letter grades are determined according to the "straight scale" given in the syllabus.

Can I use the grade calculator or what-if tool on Canvas? (No.)

Unfortunately, the grade computation and what-if tools on Canvas are misleading. Do not use them.

### Exam Curving Curve Explanation Video Watch Me!

We curve using z-scores to transform the raw distribution toward a target mean (81%) and standard deviation (9%). This results in a tighter distribution around a higher mean, while preserving its general shape.

See previous exams below as examples. We'll post updated distributions after each F23 exam.

How is this calculated?

Calculate your curved exam score using a Z-score. The max curved score is 100%. We never "curve down", meaning we keep your raw score if it is higher than the curved score.

`Z_SCORE = (RAW_SCORE - RAW_MEAN) / RAW_STDEV`
`CURVED_SCORE = TARGET_STDEV * Z_SCORE + TARGET_MEAN`
`FINAL_SCORE = max(RAW_SCORE, CURVED_SCORE)`

For example, let's say you scored 60% on an exam where mean=69% and stddev=17%. A typical curved mean and stddev 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%`
