Thanks for the response. Additionally, why did the email say the max score was 79, while the exam has the denominator of 90?

same question, why it is 90 not 79?

you can calculate the standard deviation from the 20% quantile. it should be around 13.18.

I computed the total number of possible points in the exam and it was 79, not 90. The true-false questions were mistakenly counted as if out of 2 but it does not affect the final grade I think. In other words, the grade each of us obtained is out of 79

What percentage of people is meant to not pass the course? 10%? 20%?

yes, 79 is the correct max (but as others have mentioned it is only a display error and doesn't affect anyone's points)

What is the percentage of zero exams?

What grade would a KNN have with K=4 ?
