This includes the Higher Physics past-paper archive — question papers 2006–2015 (Higher and Revised Higher), the Revised Higher specimen paper, and the corresponding marking instructions, reproduced in support of SQA qualifications on a non-commercial basis. It also covers the Higher, Advanced Higher, National 5 Engineering Science and National 5 Electronics lesson-slide PDFs: the decks are written by Mr Stewart, but the past-paper questions, extracted figures, quoted marking-instruction wording and marking-instruction links they carry are © Qualifications Scotland, reproduced for educational use.
  
  Reproduced figures, named individually (added 1 September 2026). The Higher Physics Semiconductors & p–n Junctions deck reproduces four past-paper figures, each credited on the slide it appears on: Higher Physics 2024 Paper 1 Q23 (band structures of three solids); 2024 Paper 1 Q25 (four LEDs on an a.c. supply); 2023 Paper 2 Q5(b)(iii) (energy band diagram for a red LED); and 2012 Q30(b) (a p–n junction used as a photodiode). All four are © Qualifications Scotland (SQA), reproduced for educational use.
  
  Added 2 September 2026: the Monitoring & Measuring AC deck reproduces Higher Physics 2015 Paper 1 Q17 (an oscilloscope with its Y-gain and timebase dials) and 2014 Q27 (an oscilloscope across one of two resistors); the Current, p.d., Power & Resistance deck reproduces 2022 Q19 (a mixed series/parallel resistor network), 2016 Paper 1 Q18 (a 3.0 kΩ / 7.0 kΩ potential divider) and 2011 Q9 (a Wheatstone bridge). All five are © Qualifications Scotland (SQA), reproduced for educational use.
  
  Added 5 September 2026: the Motion — Equations, Graphs & Projectiles deck reproduces no past-paper figures — its apparatus figure and all its graphs are drawn for this site (© R Stewart, 2026) — but it works seven past-paper questions and opens six of its parts with a past-paper starter, each credited on the slide it appears on: 2024 Paper 2 Q2(b), 2015 Section 1 Q2, 2013 Revised Higher Section A Q1 and 2025 Paper 1 Q1 (one for each equation of motion); 2022 Paper 1 Q2 (the light-gate slope experiment); 2022 Paper 2 Q1(a) and Q1(a)(i) (the crossbar projectile); and starters from 2008, 2011, 2012, 2013 and 2015 Section A and 2014 Revised Higher Section A. It also quotes the 2024 Higher Physics course report and the course specification v3.0 (pp. 6 and 9). All are © Qualifications Scotland (SQA), reproduced for educational use.
• Practice tests and graphing practice (classes/s3-physics/electricity1/practice-test-*.html, graphing-practice.html) — each question is either an adaptation of a National 5 Physics past-paper question, with the physics and the circuit kept and the numbers and context changed, or original to this site. Past papers and marking instructions © Qualifications Scotland (SQA), reproduced and adapted for educational use. The circuit diagrams and graphs are drawn for this site © R Stewart, 2026, as are the printable graph paper and the graphing practice's original method and data.
  
  Added 3 September 2026: the Higher Physics practice tests (classes/higher/practice-tests/) are built the same way, from Higher Physics past-paper parents (2016, 2017, 2018, 2022, 2023, 2024, 2025 and the specimen paper) with the numbers, particles and contexts changed, plus two questions original to this site. The field patterns, charged parallel plates, linear accelerator and cyclotron on those pages are drawn for this site © R Stewart, 2026.
  
  Added 5 September 2026: the Advanced Higher Physics practice tests (classes/adv/practice-tests/) are built the same way, from Advanced Higher Physics past-paper parents (2016, 2017, 2020, 2022, 2023, 2024 and 2025) with the numbers, apparatus and contexts changed, plus three questions original to this site across the A+B pair. The mass–spring apparatus, the footbridge and the damping and displacement–time graphs on those pages are drawn for this site © R Stewart, 2026.
