Standard-Model

A free single-topic revision companion for the Standard Model — the opening strand of SQA Higher Physics ‘Particles & Waves’. The first in the DrG-Physics series, offered free so you can experience the approach before purchasing further topics.

The DrG-Physics revision companion is not a worksheet. It is a structured exam-thinking guide — built around the way an SQA marker reads your script. Each worked solution leads with the relationship the examiner is looking for, substitutes cleanly, and evaluates with units. Every question carries a marker-aligned command-word tag (CALCULATE · 2 marks · STATE + JUSTIFY) so students learn what kind of answer earns each mark.

WHAT’S INSIDE

• Theory chapter on the Standard Model — quarks, leptons, hadrons, mesons, baryons, force-carrying bosons, with a clear classification diagram
• Five SQA-style questions on the Standard Model (Q1–Q5)
• Each question fully worked with marker-aligned step-by-step solutions
• Examiner’s Note after every question naming the typical pitfall
• Do/Don’t pair to reinforce the SQA marking conventions

TWO EDITIONS · ONE DOWNLOAD

• EXAM Edition — clean, concise solutions for printing and exam-style practice
• STUDY Edition — same content plus ‘Why’ reasoning panels that walk through the conceptual logic before each calculation

Both editions are included in this download.
