dibs
You are looking at Winter 2026. That term is over, so these are last term's numbers rather than seats you can take. dibs holds 1,472 sections for Winter 2026, read about 1 month ago. Separately, it has finished 195 of the 3,572 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

The registrar's own records: Fall 2021 to Fall 2025. Every instructor is pooled here.

What is inside that record

No summer session is in that record.

The table below splits them.

Historical grades for HASSON, TAMA WESTBROOK, across recorded terms. The course summary above includes all professors.

  • P 174 of 175
  • NP 1 of 175

Counts are out of 175 recorded outcomes. These are non-letter grades and do not have a GPA.

How the non-letter outcomes are counted

They are excluded from the GPA entirely rather than scored, because counting a P as a 4.0 would be a fabrication.

Why Predicted is not the Raw average

“Predicted” is shrunk toward the course average, which is itself shrunk toward the department, so an instructor with a handful of students sits near the course mean rather than topping the list.

Grade records describe outcomes. For what a course is like to take, read student reviews written on dibs below or follow the separate external review link.

Workload and assignments

Work types reported in BruinWalk reviews of this course, across recorded instructors and terms. They may differ from this term's syllabus.

dibs has not read this course’s reviews, so it cannot say what kind of work it sets. That is dibs not having looked. It is not a course without papers or exams, and the reviews linked below are the answer until dibs catches up.

In Winters

Ran in 2 of the last 4 Winters, so it turns up in Winter sometimes rather than dependably.

From the terms dibs holds, which start in Fall 2021 and exclude summer. A department can run a course in a quarter it never has before.

From the registrar's catalog

Laboratory, three hours. Corequisite: associated undergraduate lecture course in chemistry and biochemistry for physical sciences and engineering majors. Limited to Program for Excellence in Education and Research in Science (PEERS) students. Development of intuition and problem-solving skills in collaborative learning environment. May be repeated four times, but only 1 unit may be applied toward graduation. P/NP grading.

Sections in Winter 2026

Seat counts as of . That term is over, so nothing has moved since.

Final enrollment, averaged across each term's sections: between 11 and 33 a term over 9 terms, summer excluded, most recently 12 in Fall 2025. That is the shape across years, not this term, which is above.

Seats over time in Winter 2026

How each lecture has filled since dibs first saw it.

A dot is a reading where something moved: the seat count, the status, or the waitlist.

What a flat run means, and where a line starts

Flat between dots means it did not drift, it held and then jumped, and a line starts when dibs first saw that lecture rather than reaching back before it existed. A lecture that has never moved draws a flat line across the whole window, and one with two or three readings draws a line joining them, which is too few to read a trend from.

1 hour plotted. dibs read it.5 of 35 enrolled at the newest reading, about 1 month ago, with 30 left. Seats from 27 Aug 03:05 to 27 Aug 03:06, 5 to 5. The line is flat across the whole window: recorded enrollment counts match. Changes between reads may be missed. Every hour plotted carries a read, so a count that did not move here was checked and did not move.
How readings and alerts work

A reading and an hourly record are different things, and most charts here hold more of the second missing than present. dibs has taken readings of a section since long before it began keeping an hour-by-hour log of when it looked, so the empty stretches are dibs saying it was not keeping that log yet, not that it looked and found nothing. That is the age of the record and not a fault.

Seat counts show the last successful read, not live availability. Refreshes can be delayed by request limits or upstream interruptions. Watched sections receive priority, but an hourly update for every section is not guaranteed.

The registrar can change a seat count between our checks. Alerts depend on dibs detecting an opening and completing delivery; a quiet watch does not prove that no seat opened. Check the registrar before enrolling.
