That is the class itself, averaged across everyone who taught it. Who taught it, and how each of them scored, is the board below — that is what a student picking a section is actually choosing between.

What the challenge rank is made of

48thMore challenging than 48% of BC classesranked against every one we hold

90BC — “Intellectually Challenging”2 records · raw score out of 100

Boston College's own “intellectually challenging” question for this class only — students answer it positively about courses that stretched them, so it measures intellectual challenge and NOT grading, workload or quality. Almost every BC class scores high on it, which is why it is shown as a rank rather than a score.

What the workload rank is made of

—BC — “Workload”2 records — does not contribute

Boston College's workload question was not reported in these records, so there is nothing to show. That is missing data, not a light class.

Instructor	Overall	Workload	Challenge
Catherine HoarAssistant Professor · Engineering Provisional	922 records	—	48th

There is no ranking to read here: Catherine Hoar is the only instructor with evaluation records for ENGR 4420, so the number is a record, not a position. It rests on 2 records, which is thin — read it as provisional.

Bar length is the rank against every comparable record we hold, not the raw score: BC's questions all have a median around 4.5, so a raw-scale bar would be nearly full on every row and would tell you nothing. Every bar is one ink colour — nothing here is graded green or red. The hatched bars are not ratings at all: a higher number on either describes a different course, not a better one. 1 of 13 questions were not reported and are left out rather than shown as zero.

How to read this boardInstructors are ranked on their record in this class only, never on their average across everything they teach. Scores are out of 100 — Boston College's 1–5 agreement scale, ×20, the way these numbers were printed for years. Workload is BC's own five-band figure, not a number of hours, and is shown as a rank. A dash means the question was not reported, and is never a zero.
