When your IB grade lands in your inbox, it rarely arrives alone. It brings a second question that feels oddly urgent: “Okay… but what is this in GPA?”
Not because you suddenly doubt your learning, but because the world around you speaks in different academic dialects. One school says “A-,” another says “3.7,” and you’re standing there holding a neat little IB “6” like it should magically translate.
This guide breaks down IB grade to GPA and letter grade conversion in a way that’s practical, honest, and useful while you prepare for exams.
IB grade conversion checklist (fast)
Before you use any conversion table, keep these IB realities in mind:
-
Your school may (or may not) convert IB 1-7 grades into GPA.
-
Universities often interpret IB results directly, without conversion.
-
HL courses may be weighted differently depending on the institution.
-
There is no single “official” global IB-to-GPA rule.
If you want a reliable prep system while this stuff swirls around you, build it around practice and feedback: start with the RevisionDojo Questionbank and connect it to Study Notes and IB Cheatsheets.
Understanding the IB 1 to 7 grading scale
The IB uses a 1 to 7 scale for each subject, where 7 is the highest achievement level. That part is simple. What gets messy is what happens next: counselors and schools often convert those numbers into letter grades (AtoF) and a U.S.-style GPA (0.0-4.0), because those formats fit local transcripts and scholarship systems.
For your day-to-day exam prep, it helps to remember this: IB grades measure performance against criteria and mark schemes, not against how your class “feels” about the test.
If you’re trying to lift a 4 to a 5 (or a 5 to a 6), the most efficient move is usually targeted drilling. The post IB Question Bank: How to Use It Effectively shows a simple loop you can run weekly.
IB grade to GPA and letter grade conversion (common pattern)
Schools vary, but a widely used conversion pattern looks like this:
-
IB 7: typically A/A+, about 4.0 GPA
-
IB 6: typically A-/A, about 3.7 GPA
-
IB 5: typically B/B+, about 3.0-3.3 GPA
-
IB 4: typically C+/B-, about 2.7 GPA
-
IB 3: typically C/C-, about 2.0 GPA
-
IB 2: typically D/F, about 1.0 GPA
-
IB 1: typically F, about 0.0 GPA
Treat this as a translation aid, not a verdict. If your goal is a higher IB final score, conversions don’t raise your marks. Your habits do.
What students get wrong about IB conversion
Conversions are not “official” in the way you hope
There isn’t one universal IB to GPA conversion chart that every high school and every university follows. A school might convert for transcript consistency, but admissions teams are often trained to read IB results in context.
Context matters more than the number
An IB 5 in a demanding HL subject can be viewed very differently from a 5 in another context. Rigor, school profile, subject choice, and improvement trend all matter.
To handle context strategically, practice like the assessment is written: use RevisionDojo Predicted Papers and build timing with IB Biology Predicted Papers style full-paper rehearsal when available for your subject.
Weighted GPA can change the story
Some systems add extra “weight” for advanced courses. That means your converted GPA could go above 4.0 in some schools if IB HL is treated like an honors-level course.
A quick example of converting multiple IB grades into GPA
Imagine a student with these IB grades: 7, 6, 6, 5, 5, 4.
Using a common conversion:
-
7 → 4.0
-
6 → 3.7
-
6 → 3.7
-
5 → 3.3
-
5 → 3.3
-
4 → 2.7
Average GPA = (4.0 + 3.7 + 3.7 + 3.3 + 3.3 + 2.7) ÷ 6 = 3.45
If this calculation matters for your school, ask your counselor which conversion table they use. Then move your attention back to what lifts IB grades: focused review and timed practice.
How universities typically view IB scores
Many universities treat IB as a rigorous curriculum and evaluate your performance accordingly. In the UK and EU, entry offers often specify total points and HL combinations. In the U.S., universities may award credit for higher subject scores and still evaluate your transcript holistically.
The practical takeaway is calm: admissions teams usually don’t need you to “explain” the IB scale. They want to see that you can handle challenging work and improve over time.

FAQ
Is there an official IB to GPA conversion table?
No single official conversion table is used everywhere, because GPA systems are local and controlled by schools or universities. The IB reports results on the 1-7 scale, and institutions decide how (or whether) to translate that. Some high schools convert to fit transcript software or scholarship requirements. Many universities, however, evaluate IB grades directly without needing a GPA conversion. If you need a conversion for an application, ask your school counselor for the exact policy they use. Then treat it as an administrative step, not the main measure of your readiness.
Will an IB 5 hurt my chances because it “looks like a B”?
An IB 5 can map to a B range in some conversions, but that does not automatically mean it is viewed as “bad.” Universities often interpret IB performance alongside course difficulty, level (SL/HL), school context, and overall pattern. A 5 in a challenging HL course may still demonstrate strong preparation, especially if the rest of your profile is consistent. Also, improvement matters: moving from 4s to 5s across a term can signal momentum. If your goal is to push a 5 higher, focus on markscheme patterns using targeted practice and feedback. RevisionDojo’s Questionbank plus AI Chat is designed for exactly that loop.
Should I focus on GPA conversion or on raising my IB grade?
Focus on raising the IB grade, because that’s what you can control and what most schools actually evaluate in context. Conversion is mostly for paperwork, planning, and peace of mind. Your time is better spent finding why you drop marks: misunderstanding content, misreading command terms, weak structure, or time pressure. A smart weekly system is: Study Notes for clarity, Flashcards for recall, Questionbank for targeted drills, and one timed session using Predicted Papers or Mock Exams. This turns anxiety into data you can act on. The conversion table can sit in the background while your scores move in the foreground.
Final takeaway
It’s normal to want your IB grades translated into GPA and letter grades. But remember what the conversion can’t tell you: how close you are to the next boundary, which mistake patterns you repeat, and what to do tomorrow to improve.
If you want the calmest path forward, make your IB prep measurable: use RevisionDojo to connect Study Notes, Flashcards, Questionbank, AI Chat, Grading tools, Predicted Papers, Mock Exams, Coursework Library, and Tutors into one routine. Then let the conversion chart be what it was always meant to be: a reference, not a forecast.
