q2 i? Across twelve weekly tests, every weekly median reached at least the 100-point credit cap and 201 of 251 observations were at least 100 raw points. → Jin-Guo Liu 2026

q2 · i? · design · r2

Aggregate score record for all twelve weekly tests (weekly n = 18–24 by attendance), reported descriptively with the Figure 3 distribution. "201 (80.1%) were at least 100 raw points"; no inferential statistics printed.

"The raw-score distribution (Figure 3) reinforces this: every weekly median reached at least the 100-point credit cap; even the hardest week by median hit exactly 100. Across all 251 recorded student-test observations, 201 (80.1%) were at least 100 raw points."

• Students in a 13-week lecture-free course reported accepting the weekly closed-book gate and rated the format as deeper and faster than lectures — related
• Students ranked the self-paced AI-study block and the weekly closed-book test as the components they would miss most, treating tests as useful accountability — related
• The design strained on later proof-heavy topics, and students asked for better artifacts rather than fewer tests — related
