Core finding

WPH11/01 June 2023 is a past paper for Edexcel IAL Physics Unit 1 (WPH11), with 20 questions worth 80 marks. Its mark-weighted Difficulty Measure is 0.44 on a 0.20–0.75 scale, with a Difficulty Deviation of 0.21 and a mark split of 31.3% Easy, 36.2% Medium and 32.5% Hard. Algebraic complexity averages 0.33; text density and modelling average 0.43. All five measures use 34 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 34 parts carrying 80 part marks. Difficulty tags cover 34 parts, algebraic tags 34 and text-density tags 34. Tags are internal metadata, not official exam-board ratings.

Definitions and calculation

MeasurePaper valueFormula
Difficulty Measure 0.44 Σ(di × wi) / Σwi, with d = 0.20 / 0.45 / 0.75
Difficulty Deviation 0.21 √(Σwi(di − μ)2 / Σwi)
Difficulty Ratio 31.3% Easy / 36.2% Medium / 32.5% Hard marks in band / all tagged marks
Algebraic Complexity Measure 0.33 Σ(ci × marksi) / Σmarksi, with c = 0.20 / 0.45 / 0.75
Text Density and Modelling Measure 0.43 Σ(ti × marksi) / Σmarksi, with t = 0.20 / 0.45 / 0.75

wi equals the part marks, except for a Hard part worth 4 or more marks, where wi = marks0.75 to offset the accessible starter steps inside long structured questions.

Paper FAQ

How are the difficulty and 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 0.44 from 34 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 0.21, 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 31.3% Easy, 36.3% Medium and 32.5% 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.
