You are looking at Summer Session A 2026. That term is over, so these are last term's numbers rather than seats you can take. dibs holds 246 sections for Summer Session A 2026, read 35 hours ago. Separately, it has finished 400 of the 3,481 courses on its own sweep list for this term. Terms nobody is enrolling in are swept one a night in rotation, so a course with nothing here may simply not have been reached yet. Back to Fall 2026

The registrar's own records: 7,758 grades over 16 terms, Fall 2021 to Fall 2025. 3 of those terms are summer sessions, and summer sessions are counted here. Every instructor is pooled here. The table below splits them, and term averages across those 16 terms ran 2.70 to 3.62.

  • A+ 680 · 8.8%
  • A 1,553 · 20.0%
  • A- 1,294 · 16.7%
  • B+ 1,116 · 14.4%
  • B 911 · 11.7%
  • B- 680 · 8.8%
  • C+ 523 · 6.7%
  • C 415 · 5.3%
  • C- 351 · 4.5%
  • D+ 2 · 0.0%
  • D 151 · 1.9%
  • D- 6 · 0.1%
  • F 76 · 1.0%
  • P 28 of 7,818
  • NP 7 of 7,818
  • I 23 of 7,818
  • DR 2 of 7,818

Percentages are of the 7,758 letter grades. Grey bars are non-letter outcomes: passes (P), no-passes (NP), incompletes (I), and withdrawals (DR). They are excluded from the GPA entirely rather than scored, because counting a P as a 4.0 would be a fabrication. Withdrawals are the exception to "excluded": DR is not scored, but it IS counted in the D, F or W figure above, which is reported over the letter grades plus the withdrawals. Pass/no pass and S/U outcomes are outside that figure on both sides.

“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.

dibs measures outcomes: grades, seats, how fast a class fills. For what a class is like to sit in, BruinWalk has the reviews.

Reviews for CHEM 14B

What comes first

dibs has not read a class page for CHEM 14B, so it cannot say what comes before it.

Counted in courses rather than quarters: dibs does not know which of them a department lets you take together.

From the registrar's catalog

Lecture, three hours; discussion, one hour. Enforced requisite: one course from 14A, 14AE, 20A, or 20AH with grade of C- or better. Enforced requisite or corequisite: Life Sciences 30B or Mathematics 3B or 31B with grade of C- or better. Not open to students with credit for course 14BE, 20B, or 20BH. Chemical equilibria in gases and liquids, acid-base equilibrium; phase changes; thermochemistry; first, second, and third laws of thermodynamics; free energy changes; electrochemistry and its role as energy source; chemical kinetics, including catalysis, and reaction mechanisms. P/NP or letter grading.

Sections in Summer Session A 2026

You enroll in the discussion, not the lecture, so a discussion's status is the one that decides whether you get in. A lecture can read open while every discussion under it is full.

Seat counts as of : the oldest of these 7 readings. That term is over, so nothing has moved since.

Final enrollment, averaged across each term's sections: between 208 and 356 a term over 13 terms, summer excluded, most recently 345 in Fall 2025. That is the shape across years, not this term, which is above.
