It always starts the same way: you finish a practice task, you circle a score, and then your brain asks the most dangerous question in IB English -- “Is that a 6 or a 7?”
Grade boundaries don’t answer everything, but they do give you something rare in exam season: a clear target. Below are the IB English B SL grade boundaries for 2025 (Timezone 0, TZ0), plus a practical way to use them to plan revision without spiraling.

IB English B SL 2025 TZ0: quick checklist
-
Know your target mark per component, not just overall
-
Build a “buffer” above the boundary (aim slightly higher than the minimum)
-
Train the exact skills that the exam rewards: clarity, accuracy, and decision-making under time
-
Use one hub to track practice, feedback, and weak spots (RevisionDojo helps here)
If you want the fastest way to compare sessions and subjects, start at the IB Grade Boundaries hub.
IB English B SL Internal Assessment (Oral) grade boundaries 2025 TZ0
Out of 30 marks:
-
Grade 7: 27–30
-
Grade 6: 22–26
-
Grade 5: 16–21
-
Grade 4: 11–15
-
Grade 3: 6–10
-
Grade 2: 3–5
-
Grade 1: 0–2
In IB English, the oral is where “almost good” can become “clearly excellent.” The jump from a 6 to a 7 is small in marks but big in habits: precise examples, explicit links to the prompt, and a calm structure. For targeted practice, the IB English B Internal Assessment Questionbank is a strong way to rehearse under realistic constraints.

IB English B SL Paper 1 grade boundaries 2025 TZ0
Out of 30 marks:
-
Grade 7: 25–30
-
Grade 6: 22–24
-
Grade 5: 18–21
-
Grade 4: 15–17
-
Grade 3: 12–14
-
Grade 2: 6–11
-
Grade 1: 0–5
Paper 1 is the “quiet points” paper in IB English: you can gain marks just by being readable. Plan fast, keep paragraphs purposeful, and proofread like you’re hunting for lost marks. If you need volume practice with feedback loops, build timed sets in the IB English B Questionbank and reinforce structure using Study Notes.
IB English B SL Paper 2 Listening grade boundaries 2025 TZ0
Out of 25 marks:
-
Grade 7: 24–25
-
Grade 6: 19–23
-
Grade 5: 15–18
-
Grade 4: 10–14
-
Grade 3: 6–9
-
Grade 2: 3–5
-
Grade 1: 0–2
Listening can feel unfair because it disappears the moment it’s spoken. The fix in IB English isn’t “listen harder” -- it’s listening strategically: track speaker shifts, contrasts, and examples. For exam-style drills, use the Paper 2 Listening Questionbank.

IB English B SL Paper 2 Reading grade boundaries 2025 TZ0
Out of 40 marks:
-
Grade 7: 37–40
-
Grade 6: 33–36
-
Grade 5: 29–32
-
Grade 4: 25–28
-
Grade 3: 17–24
-
Grade 2: 9–16
-
Grade 1: 0–8
Reading rewards patience. Most errors come from rushing and answering what you expected the text to say. Train yourself to underline signal words (however, therefore, despite) and treat each question like a mini-proof. To practice in the right format, use Paper 2 Reading practice.
Final IB English B SL grade boundaries 2025 TZ0 (overall)
Out of 100 total marks:
-
Grade 7: 88–100

If you’re planning your target, aim above the minimum. In IB English, a small dip on a tough day happens -- a buffer protects your final grade. You can also sanity-check your progress with the IB Grade Calculator and compare thresholds on the English Language B boundaries page.
How to use these IB English boundaries to revise smarter
-
Pick one component to “stabilize” first (often listening or reading) using short daily practice.
-
Turn feedback into a loop: revise with notes, drill with questions, retest under time.
-
Simulate real pressure once per week using English B papers and then patch weak areas with Questionbank sets.
RevisionDojo is built for this: Study Notes, Flashcards, AI Chat, Grading tools, Predicted Papers, Mock Exams, a Coursework Library, and Tutors -- so your IB English prep becomes a system, not a mood.
FAQ: IB English B SL grade boundaries 2025 (TZ0)
Are grade boundaries the same for every timezone in IB English?
No, not always. Some IB subjects can have different paper versions depending on timezone, and boundaries can be reported for specific timezones (like TZ0). That’s why it’s important to use the table that matches your session and timezone, rather than copying numbers from another region. Even small differences matter when you’re aiming for a top grade. In IB English, a two-mark swing can be the difference between bands on a component. If you want to double-check you’re looking at the right place, use RevisionDojo’s IB Grade Boundaries hub to navigate by subject and session.
Should I revise based on component boundaries or the final boundary?
Use both, but start with components. The final boundary (out of 100) is your destination, but component boundaries tell you where you can realistically gain marks fastest. For example, if your writing is already stable but listening fluctuates, listening practice often gives a quicker return. In IB English, consistency across all components is usually what creates a strong overall score. Component-level goals also reduce anxiety because they turn “get a 6” into concrete targets like “hit 22/30 on Paper 1.” RevisionDojo makes this easier because you can practice each area separately using the IB English B Questionbank.
What’s the best way to improve quickly if I’m near a boundary?
Focus on the mistakes that repeat, not the topics that feel comforting. In IB English, the fastest improvements often come from process fixes: clearer paragraphs, better time splits, and answering exactly what’s asked. Do a timed attempt, then review your errors by type (misread question, weak evidence, language accuracy, rushed ending). Next, do targeted drills and immediately retest a smaller section under time. This “tight loop” beats doing random full practices and hoping. If you want a structured rehearsal, combine the Paper 2 Listening Questionbank with the Paper 2 Reading practice and track your marks against the IB English boundaries above.
Conclusion: turn IB English boundaries into calm targets
The IB English B SL grade boundaries 2025 (TZ0) aren’t a prophecy -- they’re a planning tool. Use them to set mark targets per component, build a small buffer, and practice with feedback until your score becomes predictable.
If you want everything in one place, use RevisionDojo to study with Notes, drill with the Questionbank, lock in language with Flashcards, ask AI Chat for explanations, and sharpen performance with Predicted Papers and Mock Exams. Your goal in IB English isn’t perfection. It’s reliability, on the day, under time.
