A* Checklist

Six strategies  ·  Based on Cambridge examiner reports  ·  cieinsider.com
How to use this checklist: Work through each strategy in the weeks before your exam. Tick each item when you can do it reliably — not when you’ve read about it. The gap between A and A* is almost always writing precision, not physics knowledge.
01

Mark scheme language — write physics, not impressions

02

Definitions — word-for-word recall on all 120 items

03

Command words — match response to the question type

WordWhat it requires
StateOne-line fact, no explanation
DescribeWhat happens, not why
ExplainMechanism + consequence (2 mark points)
CalculateSubstitution shown + units
DetermineMethod shown (e.g. gradient triangle)
SketchCorrect shape + key features labelled
  • I check the command word before writing any answer
  • I never write an explanation when the question says “state”
05

Graphs — best-fit line, axes, gradient

  • Both axes labelled with quantity and unit
  • Scale is sensible (uses at least half the grid)
  • Points plotted correctly (≤ 1 mm from true position)
  • Line of best fit is a single smooth line, not dot-to-dot
  • Line passes through origin only if physics requires it
  • Gradient: triangle drawn on graph, Δy and Δx values written, units carried through
04

Paper 5 — systematic marks, every series

Question 1 — Planning

  • Correct circuit / apparatus diagram
  • Independent variable named and varied
  • Dependent variable named and measured
  • At least one specific control variable
  • Method produces a range of at least 6 readings
  • Safety precaution relevant to the apparatus

Question 2 — Analysis

  • Readings to correct sig. figs. and precision
  • Calculated column with correct values and units
  • Graph axes: quantity + unit, sensible scale
  • Points plotted, best-fit line drawn
  • Gradient found using large triangle on line
  • Limitation: specific apparatus fault (not “human error”)
  • Improvement: specific method with reason
