Cambridge A Level Physics Grade Boundaries Explained

You marked a past paper and scored well. Now you want to know your grade. The trap is simple: students compare one paper's raw score to a total it was never meant to match.

This guide explains how Cambridge A Level Physics grade boundaries work, shows recent threshold marks, and gives you a clear way to estimate your own grade. No jargon. Just the numbers that matter.

Understanding Cambridge A Level Physics Grade Boundaries

What are Cambridge A Level Physics grade boundaries?

A grade boundary is the lowest total mark needed for a grade in syllabus 9702. Grades run from A* down to E. Cambridge sets these boundaries fresh each series, so they are marks, not fixed percentages.

According to Cambridge International, grade A* does not exist at the level of an individual component. It is awarded only on your overall aggregate score.

Three points define how these boundaries behave:

• Boundaries are minimum total marks, A* to E, published each series.
• No A* is awarded on a single component, only the overall aggregate.
• AS-only thresholds differ from full A Level thresholds.

How does raw mark to grade conversion work?

Each paper is marked out of its own raw total. Those marks are weighted, then added into one aggregate. The boundary is applied to that aggregate total.

So A Level physics raw mark to grade conversion means a single paper's score never maps straight to a grade. Context is everything.

The component setup shapes the whole conversion. AS students sit Papers 1 to 3, and full Cambridge AS Level Physics candidates start there before moving on:

• Full A Level candidates sit all five papers.
• Paper 4 carries the highest single weighting at 38.5%.
• Marks combine into a weighted total: 260 at A Level, 130 at AS.

Cambridge splits the marks across three assessment objectives. AO1 knowledge takes 40%, AO2 handling information takes 40%, and AO3 experimental skills takes 20%. That balance shapes where your marks come from.

What are recent CIE physics threshold marks?

Recent CIE physics threshold marks for full A Level cluster in familiar bands. In the June 2025 series, one common route set the overall A* line near 201 out of 260.

Exact numbers move every series. Treat the table below as a reference point, not a promise.

The table shows typical June 2025 overall A Level thresholds for syllabus 9702, using one standard component route. Your variant may differ by a few marks, so always confirm against the official table.

Grade	June 2025 mark (out of 260)	Approx. percentage
A*	201	77%
A	177	68%
B	153	59%
C	128	49%
D	103	40%
E	79	30%

These figures come from the published Cambridge International grade threshold table for June 2025. Other routes, like the 12/22/33 variant, shift each line by a few marks. Downloading real past papers helps you see this in practice.

What raw mark do you need for an A*?

There is no fixed A* mark. Cambridge resets it every series, so the A* line moves up or down.

It usually sits in a high band of the 260 total. Your best working target is the most recent published A* figure for your route.

Keep three habits when you chase A*:

• Read the latest A* threshold as your working goal.
• Add an 8 to 10 mark buffer for safety.
• Never compare one paper's score to the overall A* line.

Calculating and Tracking Your Grade Boundaries

How can you calculate your Cambridge grade?

Here is how to calculate Cambridge grades in plain steps. Mark each paper, weight each score, add them, then compare against the latest threshold.

Follow these four steps in order:

1. Mark each paper using the official mark scheme.
2. Apply the published weighting to each raw score.
3. Add the weighted scores into one aggregate total.
4. Compare that total to the latest threshold table.

Worked example: suppose your weighted total is 180 out of 260. In the June 2025 table, that clears the A line of 177. So you would sit in the A band for that route.

Always use the same session and the same variant. Never mix a June paper with a November threshold. That mix is how good scores turn into wrong grades.

This is the safest way to read Cambridge A Level Physics grade boundaries against your own marks. If your estimate keeps falling short, targeted help from Cambridge A Level Physics tutors can close the gap fast.

Why do grade boundaries change every year?

Boundaries move to keep the standard steady. A harder paper gets lower cut-offs. An easier paper gets higher ones. That way, equal performance earns the same grade across different years.

The mechanism has a clear name and logic:

• Cambridge calls it grade protection; Ofqual calls it comparable outcomes.
• Boundaries are set after every script is marked.
• Past boundaries are useful guides, never guarantees.

Cambridge looks at paper difficulty and how the whole cohort performed, then sets each line. This is why last year's mark is a hint, not a rule.

Where are Cambridge A Level Physics grade boundaries published?

Official Cambridge A Level Physics grade boundaries live on the Cambridge International website. The June 2026 grades were released on 11 August 2026. Third-party trackers are convenience tools, not the source of truth.

Use the official source, then read it correctly:

• Find the threshold table for syllabus 9702.
• Match your exam session and your variant.
• Use trackers to estimate, then confirm officially.

The Cambridge PDF lists many syllabuses at once. Scroll to 9702, then match the row to your component route. That single check keeps your estimate honest.

Conclusion and Next Step

One idea prevents most results-day panic. Cambridge A Level Physics grade boundaries apply to the weighted aggregate, not a single paper, and they reset every series. So the current official table is your only reliable target.

Your next step is simple. Bookmark the official 9702 threshold page. Then mark timed past papers and plot each score against the latest boundaries. That habit turns guesswork into a clear, trackable target.
