A Level to IB Score Estimator
Use this tool to estimate your IB Diploma equivalent score (out of 45) from A Level grades. This is an unofficial guide for planning and comparison only.
Method: A Levels are mapped to approximate HL points, then projected to a full IB Diploma profile (HL + SL + core points).
How this A Level to IB conversion calculator works
Students often need to compare different qualification systems when applying to international universities. This calculator estimates an IB Diploma score by converting your A Level grades into an IB-style structure. It is especially useful if you are:
- Applying to universities that list IB requirements
- Comparing course competitiveness across countries
- Planning target grades and admission strategy
- Trying to understand where your profile sits academically
Grade mapping used in this tool
We convert each A Level to an approximate IB Higher Level (HL) score using the following mapping:
- A* → 7
- A → 6
- B → 5
- C → 4
- D → 3
- E → 2
- U → 1
From there, the calculator estimates Standard Level (SL) performance and adds a projected core score (TOK/EE/CAS equivalent impact) to produce a total out of 45.
Why conversion is approximate (not official)
A Levels and the International Baccalaureate are structured differently. A Levels are usually specialized and deep in fewer subjects, while IB requires breadth across six subjects plus core requirements. Because of this, no universally official one-to-one conversion exists for every admissions context.
Universities may interpret equivalence differently depending on:
- Country and admissions system
- Program selectivity (medicine, engineering, law, etc.)
- Required subjects and whether they are HL/SL in IB terms
- Predicted grades vs final achieved grades
How to interpret your estimated IB score
Score bands
- 40–45: Highly competitive profile for very selective programs
- 35–39: Strong profile for many competitive universities
- 30–34: Solid profile for a broad range of courses
- 24–29: Meets many standard thresholds, depending on subject requirements
- Below 24: Usually below typical IB Diploma pass benchmarks
Use a range, not a single number
Admissions outcomes are never based on one score alone. That is why the calculator also provides an estimated range (for example, 34–38). Treat this as a planning guide and always verify entry requirements directly with the university.
Example conversion scenario
Suppose you enter A*, A, and B. The tool maps these to strong HL scores and builds an IB estimate that typically lands in the mid-to-high 30s. This can help you quickly compare against offers such as “36 points with 6,6,5 at HL.”
Practical tips for applicants
- Check both total score and subject-specific requirements
- For competitive programs, prioritize top grades in required subjects
- If you have four A Levels, highlight your strongest three for IB-style HL comparison
- Use personal statement, references, and super-curricular activities to strengthen your application profile
FAQ
Is this calculator accepted by universities as official?
No. It is an estimation tool for student guidance. Universities set their own official equivalence standards.
Can I use predicted grades?
Yes. It can be useful for planning, but predicted and final grades can lead to different admissions outcomes.
What if I take 4 A Levels?
Enter all four. The calculator uses your strongest three for HL-style estimation and notes that an additional subject may strengthen your overall academic profile.
Does this include UCAS points?
Yes, the result includes a UCAS tariff subtotal for the grades you enter, so you can compare both IB-style and UCAS-style indicators side by side.
Final note
Use this A Level to IB conversion calculator as a quick, practical benchmark while researching university entry requirements. For final decisions, always rely on official admissions guidance from the institution you are applying to.
