Algebraic complexity averages 0.32; text density and modelling average 0.46. All five measures use 30 part-level tags, not candidate results. Every question row below repeats them and opens the Interactive Practice Hub for that question. ## Difficulty & complexity profile All five measures are mark-weighted and calculated from 30 parts carrying 82 part marks; the published paper total is 80 marks. Difficulty tags cover 30 parts, algebraic tags 30 and text-density tags 30. Tags are internal metadata, not official exam-board ratings. - **Difficulty Measure**: 0.45 — 0.20–0.75 · nearer Medium - **Difficulty Deviation**: 0.16 — 0 = uniform; higher = more mixed - **Difficulty Ratio**: 18.3 / 61.0 / 20.7 — % Easy / Medium / Hard - **Algebraic Complexity Measure**: 0.32 — 0.20–0.75 · nearer Low - **Text Density and Modelling Measure**: 0.46 — 0.20–0.75 · nearer Medium Scale: Easy 0.20 · Medium 0.45 · Hard 0.75, and Low 0.20 · Medium 0.45 · High 0.75 for the two complexity measures.

--- | --- | --- | | **Difficulty Measure** | 0.45 | Σ(d_i × w_i) / Σw_i, with d = 0.20 / 0.45 / 0.75 | | **Difficulty Deviation** | 0.16 | √(Σw_i(d_i − μ)^2 / Σw_i) | | **Difficulty Ratio** | 18.3%

Modelling Measure** | 0.46 | Σ(t_i × marks_i) / Σmarks_i, with t = 0.20 / 0.45 / 0.75 | w_i equals the part marks, except for a Hard part worth 4 or more marks, where w_i = marks^0.75 to offset the accessible starter steps inside long structured questions. ## Question list Each measure is recalculated from the parts of that question and uses the same weights as the paper profile. | Question |

complexity measures calculated?** Each part is weighted by its official marks. Difficulty uses Easy 0.20, Medium 0.45 and Hard 0.75; algebraic complexity and text density and modelling use Low 0.20, Medium 0.45 and High 0.75. A Hard part worth 4 or more marks is down-weighted to marks^0.75, so the accessible starter steps inside a long structured question do not inflate the difficulty result. This paper's Difficulty Measure is 0.45 from 30 parts. **What does the Difficulty Deviation show?** It is the mark-weighted standard deviation of the part difficulty values around the paper mean. A value of 0 would mean every tagged part has the same difficulty; this paper's deviation is 0.16, so its parts are more mixed than a single-level paper. **Is the Difficulty Ratio based on question counts or marks?** It is based on official marks, not question counts. This paper's shares are 18.3% Easy, 61.0% Medium and 20.7% Hard; the three shares sum to 100% before rounding. **Are these official difficulty ratings?** No. They are derived from the platform's part-level difficulty and static-question-profile tags. They are not exam-board grade boundaries and are not calculated from candidate outcomes. Use them to compare the demand profile of papers, not to predict a grade. **Why does each question row show its own measures?** Each row recalculates the same mark-weighted formula from that question's parts. A single-part MCQ therefore shows the tag value directly, while a multi-part structured question blends the tags of its parts using the same Hard-part decay as the paper profile. --- Full page with native tables, bar charts and Practice Hub links: https://www.examsci.com/past-papers/edexcel-ial/physics/physics-unit-1-wph11/2019-june-wph11-01/
