Grades with this instructor
You are looking at Spring 2026.
That term is over, so these are last term's numbers rather than seats you can take.
dibs holds 21 sections for Spring 2026, read about 1 month ago. Separately, it has finished 15 of the 3,617 courses on its current checking list for this term. Future-term coverage is incomplete, so a course with nothing here may simply not have been reached yet.
Back to Fall 2026
PANG, JOHNNY
3,667 letter grades across 5 courses, Fall 2022 to Fall 2025. Course by course the average runs 3.48 to 3.91, so read the course, not the person.
Dibs may hold a second record for this person. Every figure here counts only the grades filed under this spelling, PANG, JOHNNY. The registrar's records also name PANG, JOHNNY W, carrying 1,202 more letter grades. The sources spell the name two ways and dibs keeps both rather than guess that they are the same teacher.
Teaching in Spring 2026
No sections appear in the available Spring 2026 schedule. This does not establish future teaching plans. The record below is from earlier terms.

Grades with this instructorRaw is the average actually awarded. Predicted pulls it toward the course average, and then toward the department's, in proportion to how few grades there are, so twelve students cannot outvote six terms. A range is the share who got an A minus or better. D, F or W is the share who finished with a D or an F, or withdrew. There is no single average for this person: one figure over every course would be weighted by students, not by course, and the largest lecture would stand for all of them.
What students say
dibs measures outcomes: grades, seats, how fast a class fills. For what a class is like to sit in, BruinWalk has the reviews.
