QCE Physics

QCE Physics hardest topics

Across 19,741 marked attempts on AusGrader, QCE Physics students average 60.7% on questions taken from board external papers. The lowest average of any command verb is calculate on 47.7%, and the verb that costs the most marks is determine, which carries 30.9% of the paper against 23.1% for calculate. These are self-selected users practising when they chose to, not the QCAA cohort under exam conditions.

How to read these numbers

  • The figures are AusGrader users' marked attempts, not QCAA results. They corroborate what the board publishes about this subject and do not stand in for it.
  • Any cut with fewer than 50 attempts is withheld, which on this page is 2 papers, 14 dot points and 20 verbs. Every figure shown carries its attempt count.
  • Scores cover questions mapped to the QCE Physics syllabus from any board's external papers, which is why the sample is larger than the 12 QCAA papers alone. The paper table below is the exception and uses QCAA papers only.
  • Internal assessment and school-uploaded exams are excluded throughout, so these averages differ from the ones on QCE Physics performance stats, which count every attempt.

The lowest average belongs to the 2023 Paper 2 on 46.4% from 122 attempts, and the highest to the 2024 Paper 1 on 73.5% from 587 attempts. A paper's average reflects both how hard it was and who chose to sit it, so treat the spread as a guide to which papers make demanding practice.

UnitAverageAttempts

An attempt counts once per unit, so a question assessed across two units appears in both rows and the column adds to slightly more than 19,741.

Calculate has the lowest average on the page at 47.7%, and it is not where the marks go. Determine averages 56.5% but carries 30.9% of the paper against 23.1%, so it puts 13.4 marks per 100 at risk against 12.1. For the plain ranking of verbs by score, and what QCAA has said about each, read the QCE Physics study guide.

Frequently asked questions

Which QCE Physics past paper do students score lowest on?

The 2023 Paper 2, averaging 46.4% across 122 marked attempts on AusGrader. The 2024 Paper 1 is the highest on 73.5%.

Which QCE Physics dot points give the best return on revision time?

3.1.1.4 (2.4 marks at risk per 100), 4.2.1.6 (2.3 marks at risk per 100) and 3.1.2.9 (2.3 marks at risk per 100). Marks at risk combines a dot point's share of paper marks with the marks students drop on it, so it ranks by recoverable marks and not by score alone.

How many attempts is each QCE Physics figure based on?

19,741 marked attempts overall, with the per-row count shown in every table. Any cut below 50 attempts is withheld instead of published.

Do these averages show how the QCAA cohort performed?

No. They are AusGrader users' marked attempts, a self-selected group practising when they chose to and often without exam timing. They corroborate what QCAA publishes about this subject and do not replace it.
