Students can handle the difficulty. They question the assessment.

The finding

When a course scores poorly, the instinct is to assume it is too hard. The data points somewhere else. Course Difficulty, which captures how hard a course is versus what students expected, scores 6.9 out of 10, and only 7% of responses sit in the bottom band. Raw difficulty is rarely where students struggle.

The friction shows up next door. Alignment with Learning Objectives, which asks whether the assessment measures what was taught and what students actually understand, scores 6.3 out of 10. Here 24% of responses fall in the bottom band, roughly 1 in 4. Students are telling us they can cope with hard material. What a substantial minority push back on is whether the exam, lab or test is a fair measure of what they know.

Where students rate alignment lowest 2.5

"The tests stopped measuring knowledge and started measuring writing speed. Twenty minutes isn’t enough to show what you understand."

"You get marked down for tiny errors, a wrong sign or a single digit, so the grade doesn’t reflect what you actually know."

"The lab assessment doesn’t make sense. Labs should be where you learn by doing, but they’ve become a weekly pressure to finish, not to understand."

"Assessment is fragmented and overloaded, two midterms, a test, two labs and a project, and the syllabus grew on top of it."

What the lowest scores have in common

Read the bottom band together and a consistent theme appears, and it is not difficulty. It is assessment validity. Three patterns recur. Assessment that rewards speed or penalises trivial errors, so a tight time limit or a single wrong digit drives the grade rather than understanding. Labs that have shifted from a place to learn by doing into a graded weekly pressure to finish. And assessment that is fragmented and overloaded, where midterms, tests, labs and projects stack on top of a syllabus that keeps growing.

None of these complaints is about content being too demanding. Every one is about whether the instrument in front of the student measures the right thing. That distinction matters because the two problems call for opposite responses. Making a course easier does nothing for a student who understands the material but cannot demonstrate it in twenty minutes. Fixing the assessment does.

What it means for institutions

1. Separate difficulty from alignment in how you read scores. A low score on alignment usually flags an assessment-design problem, not a curriculum that is too hard. Treating it as “make the course easier” misreads what students are saying.
2. Audit assessment for validity. Ask of each instrument whether it measures understanding, or speed, neatness and error-avoidance. Time limits and tiny-error penalties are the usual culprits, and they are fixable without lowering the bar.
3. Watch assessment load. When midterms, tests, labs and projects stack up, students experience even well-pitched content as unfair. Coordinate assessment across modules so the total burden is visible and deliberate, not accidental.

How we measure it

Course Difficulty and Alignment with Learning Objectives are scored on a 0 to 10 scale, with the bottom band capturing the lowest-rating responses. The difficulty figure (6.9, 7% in the bottom band) draws on the broad response base. Alignment (6.3, 24% in the bottom band) is measured on a smaller, recent sample, so read it as the consistent theme among the lowest-rating students rather than a sector-wide headline. The quotes are verbatim, de-identified, and translated from the original where needed, drawn from responses in the lowest band (mean score around 2.5).
