Select Your International A-Level Board

Choose the qualification route you want to estimate. Pearson IAL uses UMS totals; Cambridge can use PUM percentages or raw threshold estimates.

🧮 How this calculator works
Percentage estimate: P = (score ÷ maximum score) × 100.
Pearson IAL UMS estimate: A = 80%, B = 70%, C = 60%, D = 50%, E = 40%; A* requires the A boundary plus the A2 high-mark condition when A2 UMS is available.
Cambridge PUM estimate: A* = 90–100, A = 80–89, B = 70–79, C = 60–69, D = 50–59, E = 40–49.
  • Use UMS mode when your Pearson Edexcel IAL result gives unit UMS scores.
  • Use PUM mode when your Cambridge result shows a percentage uniform mark.
  • Use raw threshold mode only for a quick estimate before official thresholds are checked.
Quick guidance

Is this an official grade?

No. It is a practical estimate. Official grades depend on the exam board’s published boundaries, unit rules, and final certification rules.

Why does Pearson IAL ask for A2 UMS?

A* is not only an overall high score; it also needs a high score in the A2 part of the qualification.

Should I use raw marks or PUM for Cambridge?

Use PUM if it is shown on your result. Use raw marks only with the correct threshold table for your syllabus, component route, and exam series.

ℹ️
Important: This International A-Level Grade Calculator is built for fast student guidance. Pearson Edexcel IAL final grades can depend on UMS aggregation and A2 conditions. Cambridge International grades depend on the official threshold table, syllabus code, component combination, and series. Always verify final results against the official Pearson Edexcel or Cambridge International documents.

What Is an International A-Level Grade Calculator?

An International A-Level Grade Calculator estimates a student’s grade from International AS, International A2, or full International A-Level marks. It can work with Pearson Edexcel IAL UMS marks, Cambridge percentage uniform marks, or raw marks compared against grade thresholds.

A strong calculator should let you choose the exam board, subject, qualification stage, unit or paper rows, mark type, grade boundary set, and UCAS tariff estimate.

The result is an educational estimate unless the calculator uses the official boundary or threshold document for the exact syllabus, unit route, component combination, and exam session.

How International A-Level Grades Are Calculated

International A-Level grades are calculated by combining marks from the required units, papers, or components. Pearson Edexcel IAL qualifications often use UMS aggregation across units, while Cambridge International uses grade thresholds and may report percentage uniform marks.

Weighted mark formula:
Unit percentage = marks scored ÷ total marks
Weighted contribution = unit percentage × unit weighting
Final weighted score = sum of all weighted contributions

If UMS mode is selected, the calculator should compare the total UMS against the relevant UMS grade scale. If raw-mark mode is selected, the calculator should compare the raw total against the selected official threshold table or a clearly labelled generic estimate scale.

International AS vs International A2 vs Full A-Level

International AS, often called IAS, is the first part of many International A-Level routes. International A2, often called IA2, is the second part. A full International A-Level usually combines AS and A2 performance.

International AS / IAS Usually represents the first half of the qualification. AS grades commonly run from A to E and normally do not include A*.
International A2 / IA2 Usually represents the second half of the qualification. For some modular routes, A2 performance is important for A* eligibility.
Full International A-Level Combines the required AS and A2 units or components. Full A-Level grades usually run from A* to E.
Certification route matters The same subject can have different rules depending on board, syllabus, unit combination, and exam session.

Raw Marks, Weighted Marks, and UMS Explained

Raw marks are the actual marks scored on a paper or unit. Weighted marks adjust those raw marks according to how much the unit contributes to the final grade. UMS, or uniform mark scale, converts raw performance into a standardised mark scale so that marks from different exam sessions can be combined more fairly.

Mark Type What It Means When to Use It
Raw mark The actual mark scored on a paper or component. Use with official raw grade thresholds.
Weighted mark A raw score adjusted by the paper or unit weighting. Use when papers contribute different percentages.
UMS A converted mark used in some modular qualifications. Use for Pearson Edexcel IAL unit aggregation.
PUM Percentage uniform mark, commonly used in Cambridge reporting. Use when Cambridge reports a percentage uniform mark.

Grade Boundaries and Thresholds Explained

Grade boundaries or thresholds are the minimum scores needed for each grade in a particular exam session. They can change every session because papers vary in difficulty and awarding bodies review performance before finalising grades.

For Pearson Edexcel IAL, students often need to consider UMS totals and, for A*, the relevant A2 performance requirement. For Cambridge International, students should check the official threshold table for the exact syllabus code, component combination, and exam series.

A generic estimate scale is useful for planning, but it should not be treated as an official result.

Cambridge vs Pearson Edexcel International A-Level

Cambridge International and Pearson Edexcel International A-Level both serve international students, but their grading workflows can differ. The calculator should therefore ask the student to choose the correct board before entering marks.

Feature Cambridge International Pearson Edexcel IAL
Common mark type Raw marks, thresholds, and percentage uniform marks Raw marks converted to UMS for modular aggregation
AS / A2 structure Depends on syllabus and route IAS and IA2 units are commonly used in modular IAL routes
A* estimate Depends on official thresholds or PUM band Typically depends on overall A performance plus A2 UMS condition
Best calculator mode PUM mode or official threshold mode UMS mode with unit rows

How to Use the Calculator

  1. Select the exam board: Cambridge International or Pearson Edexcel IAL.
  2. Select the subject.
  3. Choose IAS, IA2, or full International A-Level.
  4. Choose raw marks, weighted marks, UMS mode, or PUM mode.
  5. Add one row for each unit or paper.
  6. Enter marks scored and total marks for each row.
  7. Enter the weighting for each unit or paper.
  8. Check that total weightings equal 100%.
  9. Select an official boundary/session if available.
  10. Calculate the estimated grade, points needed for the next grade, and UCAS tariff estimate.

International A-Level Grade Example

Suppose a student has three International A-Level units:

Unit / Paper Marks Scored Total Marks Weighting Weighted Contribution
Unit 1 72 100 30% 21.6%
Unit 2 68 100 30% 20.4%
Unit 3 84 120 40% 28.0%

The final weighted score is 70.0%. The estimated grade then depends on whether the student is using Pearson UMS, Cambridge PUM, official raw thresholds, or generic estimate mode.

FAQs

What is an International A-Level Grade Calculator?

It is a tool that estimates International AS, International A2, or full International A-Level grades from marks, unit totals, weightings, UMS, PUM, or official grade thresholds.

How are International A-Level grades calculated?

They are calculated by combining required units, papers, or components. Pearson IAL often uses UMS aggregation, while Cambridge International uses official thresholds and may report percentage uniform marks.

What is the difference between IAS and IA2?

IAS is the International AS part of the qualification. IA2 is the second part that contributes to the full International A-Level. In some modular routes, IA2 performance is important for achieving A*.

What is UMS in International A-Level?

UMS means uniform mark scale. It converts raw exam performance into a standardised mark scale so unit results from different sessions can be combined.

What percentage is an A* in International A-Level?

There is no single universal raw percentage for A*. In Pearson IAL UMS routes, A* usually depends on reaching the A boundary overall and meeting a high A2 condition. In Cambridge routes, the A* estimate depends on PUM or official thresholds.

Do grade boundaries change every session?

Yes. Grade boundaries and thresholds can change between sessions because exam papers vary in difficulty and awarding bodies set final standards after marking.

Can I use this for Cambridge International A-Level?

Yes. Use Cambridge mode, then choose PUM mode if you have a percentage uniform mark or threshold mode if you have the official grade-threshold table.

Can I use this for Pearson Edexcel IAL?

Yes. Use Pearson Edexcel IAL mode and enter the relevant UMS or unit scores. For A* estimates, include the IA2 or A2 UMS information where required.

Is this calculator official?

No. It is an educational estimate unless it uses the official board documents for the exact subject, unit route, component combination, and exam session.
