The registrar's own records: 154 grades over 10 terms, 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, and term averages across those 10 terms ran 3.28 to 3.90.

Percentages are of the 52 letter grades. Grey bars are non-letter outcomes: passes (P).
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
Reported assignments across instructors and terms. This term's syllabus may differ.
What the work looks like
- 2 exams, 3 mentions in past reviews
- Quizzes mentioned, no number given, 3 mentions in past reviews
- 1 lab, 1 mention in past reviews
Based on 10 reviews; source checked about 2 months ago. dibs counts only what a review actually states, so a kind of work nobody mentioned is absent rather than zero.
In Springs
Ran in 2 of the last 4 Springs, so it turns up in Spring 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, one hour. Enforced corequisite: course 3. Investigations and data analysis supporting material in course 3, including interpretation of meteorological data, use of modern visualization tools to understand weather, and critical analysis of historical hurricane data. P/NP or letter grading.

From the people who took it
Student reviews
What taking A&O SCI 3L was like: the work, the teaching, and what students wish they’d known.
Your experience could be the first.
No student reviews are available to read on dibs for this course yet. Took it? Tell the next person what helped, what was hard, and how you spent your time.
Looking for more perspectives?
External reviews are separate and do not count toward the dibs rating.
Seats over time in Spring 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.

How readings and alerts work
Dated seat counts can be available even when hourly check history is missing. Gaps do not show whether seats changed between observations.
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.
