A perfect 45 points is reached by only a small fraction of IB students worldwide each year. But the strategies that push a score toward 45 are the same ones that move a 32 to a 36, or a 36 to a 40. This guide covers those strategies practically, with a clear look at how IB grading actually works. The goal is not to fixate on a number. It is to understand what genuinely moves the score, and do those things consistently across two years.

Here are grounded strategies to work toward a 45-point IB score, with a clear look at how the grading actually works.

How the IB Grading System Works

The IB grading system scores the Diploma out of 45 points, combining six subjects with a core. Knowing how to score well in IB starts here, since every target rests on how the points add up.

The 45-Point Breakdown

Each of the six subjects is graded from 1 to 7, giving up to 42 points. Theory of Knowledge (TOK) and the Extended Essay (EE) add up to three more points through a points matrix, for a maximum of 45. The split shows why the Higher Level subjects and the core deserve the most attention.

What It Takes to Pass

A learner earns the Diploma with at least 24 points, subject to conditions. No subject can be graded 1; the three Higher Level subjects must total at least 12 points, the Standard Level subjects at least 9, and the core must be complete. Falling below any of these means the Diploma is not awarded, even when the total looks healthy.

What Counts as a Good and Average IB Score

A good IB score is best judged against the global picture, since the number alone means little without context. Most families use the worldwide average as their baseline.

The Global Average and What Beats It

The average IB score sits around 30 out of 45, so a score in the mid-30s is already strong. Anything above 40 is excellent, and a perfect 45 is reached by only a small fraction of learners each year. Aiming for a personal best, rather than fixating on 45, keeps effort steady and healthy.

What Different Scores Signal

The table below sets out how each band tends to read to a family and to universities.

Strategies to Maximise the IB Score

A good IB score strategy comes from steady habits, not last-minute effort. The approaches below help a learner reach their highest possible score, and practical tips for thriving in the IB add to them.

Habits That Lift Every Score

• Master the Higher Level subjects, since they demand the most and carry real weight.
• Treat Internal Assessments seriously, as they are marked to known rubrics and lift subject grades.
• Revise consistently across two years rather than cramming before examinations.

Winning the Three Core Points

Target the three core points with a strong Theory of Knowledge essay and a well-planned Extended Essay. The points come from a matrix, so a steady grade in both beats a brilliant essay paired with a weak one. Starting the Extended Essay in the first year gives time to research, draft, and refine it properly.

Exam Technique and Timing

Past papers and mock examinations build exam technique and timing, which protect marks under pressure. Choosing subjects that fit genuine strengths and university goals also keeps motivation high across the two years. Marking a few papers against the official rubric shows exactly where marks are won and lost.

Making Internal Assessments Count

Internal Assessments form a meaningful share of each subject grade and are marked to published rubrics. Drafting early, acting on teacher feedback, and matching the rubric point by point turn them into reliable marks.

Keeping a Healthy, Steady Pace

A top score comes from consistent effort, not exhaustion. Regular breaks, enough sleep, and a manageable weekly rhythm keep a learner sharp across a demanding two years.

When to Start Working Toward a High Score

A strong IB score is built over two years, not in the final term. Starting early turns a distant target into a series of manageable steps.

The First Year

Use the first year to settle into Higher Level subjects and build steady study habits. Beginning the Extended Essay early, rather than leaving it to the second year, takes real pressure off later.

The Final Year

The second year is about consolidation and exam readiness. Regular past papers, timed practice, and finishing Internal Assessments on schedule protect the score when it matters most.

Common Mistakes That Cost IB Points

Some points are lost not to difficulty but to avoidable slips. Knowing the common ones helps a learner protect a strong score.

• Leaving the Extended Essay and Internal Assessments too late, then rushing them.
• Neglecting Theory of Knowledge, which quietly costs core points.
• Underestimating a Higher Level subject that carries heavy weight.
• Cramming for finals instead of building understanding across two years.

How Universities Look at the Score

Universities rarely read the total in isolation, so a strong number is only part of the picture. A look at whether IB learners perform better at university shows how scores translate into outcomes.

• Higher Level grades, weighted heavily for the fit with the intended degree.
• The match between subjects and the course, such as Mathematics and Physics at Higher Level for engineering.
• Predicted grades a school submits ahead of final results.
• The overall total, read alongside these details rather than on its own.

How JBCN Supports High Scorers

At JBCN International School, the IBDP is supported by experienced educators, and the results reflect it. JBCN learners have maintained a 100% pass rate, with an average score around 37, well above the global average, and more than a quarter of learners scoring above 40 points for the batch of 2026.

The support behind those scores is practical:

• Faculty includes IB examiners in subjects such as Biology, Chemistry, and the Extended Essay, giving direct insight into marking rubrics.
• Extended Essay and Internal Assessment mentoring is built into the programme.
• University counselling from Grade 9 aligns subject effort with target courses.

Take the Next Step

The clearest way to understand how a school lifts scores is to meet the mentors who guide the Extended Essay and Internal Assessments. A short campus visit shows how that support would work for your child.
