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

37thMore challenging than 37% of BC classesranked against every one we hold

88BC — “Intellectually Challenging”14 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

34thMore work than 34% of BC classesranked against every one we hold

49BC — “Workload”14 records · raw score out of 100

Boston College reports workload for this class only as one of five bands, not as a number of hours, and it does not publish what the bands mean — so this site will not translate it into hours. Higher means more work, which is not the same as worse.

This course is the first of a two-semester introductory-level sequence in biochemistry. Topics in the first semester focus primarily on the structure, function and biosynthesis of the major biomolecules. Additionally, this course provides an introduction into thermodynamics, kinetics and mechanisms of enzyme-catalyzed reactions. Topics in the second semester will concentrate on metabolism of carbohydrates, fatty acids, and amino acids; biochemical transformations of these nutrient molecules leading to fuel production will be discussed along with regulatory mechanisms of various metabolic processes.

Scores are real averages. The order also accounts for how many records back each one — the count is under every score — so one perfect review does not outrank a semester of them.

How this board is orderedPositions account for how many records stand behind each number, so one perfect review does not outrank a semester of them. Every score shown is the real average — only the ordering is adjusted. The comparison here is the class itself: a thin record is read against how this class was rated overall, not against the university.

Every instructor with an evaluation record for this class is on this board — it is not a top ten, and nothing is hidden behind a “show more”. Overall is the instructor's blended score for THIS class only, and its one contributing source is Boston College's evaluations for the sections in the row's record count — nothing on this board is an average across the other things they teach. Workload and Challenge are RANKS against every class we hold, not scores: BC's questions all sit near the top of the 1-5 scale, so a raw number would put almost every row in the high eighties and tell you nothing. Challenge is BC's “intellectually challenging” item, which students answer positively about courses that stretched them — it is not a measure of difficulty or grading. Neither column is ever marked better or worse. 7 of 8 rows are marked provisional: fewer than 3 records stand behind the number. That is thin evidence, not a bad instructor — the record count is in every row. The RateMyProfessors column is an instructor's overall figure across everything they teach; that site has no course dimension, so it is shown for information and kept out of the ranking.

WorkloadHow much work the course took outside class, on Boston College's five-band scale — the band boundaries are not published, so this is not a number of hours.

Intellectually ChallengingThe course was intellectually challenging.

809th pctl

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.

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.
