Sections & times

Lab.

Fall 2026: 6 sections. All of them are open. The oldest of these readings was 23 minutes ago.

Also listed as EC ENGR M116L (closed by the department, majors only): the same class, and each department holds its own seats and its own grade history.

Grades

3.94

Average grade awarded in COM SCI M152A. Not a student rating: this is what the grades were.

97%

of the 2,008 letter grades

D, F or W

0.3%

Taken pass/no pass

the registrar has this letter grade only this term

The registrar's own records: 2,008 grades over 13 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 13 terms ran 3.83 to 3.99.

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

  • A+ 427 · 21.3%
  • A 1,394 · 69.4%
  • A- 127 · 6.3%
  • B+ 33 · 1.6%
  • B 11 · 0.5%
  • B- 6 · 0.3%
  • C+ 1 · 0.0%
  • C 2 · 0.1%
  • D+ 1 · 0.0%
  • F 6 · 0.3%

Percentages are of the 2,008 letter grades. Grey bars are non-letter outcomes.

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.

What comes first

The chain dibs can see is 1 course long before COM SCI M152A. dibs has read a class page for every course in it.

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

In Falls

Ran in 5 of the last 5 Falls.

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

(Same as Electrical and Computer Engineering M116L.) Laboratory, four hours; outside study, two hours. Enforced requisite: course M51A or Electrical and Computer Engineering M16. Hands-on design, implementation, and debugging of digital logic circuits, use of computer-aided design tools for schematic capture and simulation, implementation of complex circuits using programmed array logic, design projects. Letter grading.

Sections in Fall 2026

Seat counts as of : the oldest of these 6 readings. Seat readings are snapshots, not live availability. Their timestamps show when dibs last checked.

Final enrollment, averaged across each term's sections: between 20 and 30 a term over 13 terms, summer excluded, most recently 20 in Fall 2025. That is the shape across years, not this term, which is above.

Seats over time in Fall 2026

How each lecture has filled since dibs first saw it. This course runs 6 lectures; the legend under the chart picks one.

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

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.
