IB Diploma Guide: How to Prepare and What to Expect
A practical IB Diploma guide: the six subjects, the core of TOK, EE and CAS, the 45-point scale, and the pass conditions you must meet.

The direct answer: the IB Diploma Programme is a two year course for students aged 16 to 19 that requires six subjects plus a core of Theory of Knowledge, the Extended Essay, and Creativity Activity Service, and it is scored out of 45 points with a pass mark of 24 1. This guide explains the structure, the core, the scoring, and a study routine you can start now.
A note on names: the IB Diploma Programme is run by the International Baccalaureate, a separate organization from the College Board. StudyInk is not affiliated with or endorsed by the International Baccalaureate.

What the IB Diploma Requires
The Diploma is a single programme, not a set of separate courses you pick at random. Understanding the shape early helps you choose subjects wisely and avoid overload later.
The six subject groups
Students choose one subject from each of six groups: studies in language and literature, language acquisition, individuals and societies, sciences, mathematics, and the arts, or a second subject from another group. Three are taken at Higher Level with about 240 teaching hours, and three at Standard Level with about 150 hours 2. Those hour counts explain why Higher Level feels heavier: the depth is real, not decorative.
The core components
The core is what distinguishes the IB from many other pre university routes. Theory of Knowledge asks how we know what we claim to know. The Extended Essay is an independent research paper of up to 4,000 words. Creativity Activity Service is a portfolio of activity across the three strands, completed over the two years, often as an 18 month commitment 2.
The core is graded too. Theory of Knowledge and the Extended Essay together can add up to 3 points to the total through a published matrix 1. Skipping the core is not an option; CAS must be completed and a failing grade in either TOK or the EE can block the Diploma regardless of your subject total.
How the IB Is Scored
The point total decides the award. Six subjects give up to 42 points, and the core contributes up to 3 more through the matrix combining Theory of Knowledge and the Extended Essay.
The 45-point structure
Each subject is graded on a 1 to 7 scale. Three Higher Level and three Standard Level subjects give a maximum of 42. The final three points come from the TOK and EE matrix. A perfect 45 is rare, and a score in the high 30s is already strong for many universities.
The pass conditions
A candidate needs at least 24 points, but the total is not the whole story. The published conditions also require no grade 1 in any subject, no more than two grade 2s, no more than three grades of 3 or below, at least 12 points from Higher Level subjects, at least 9 from Standard Level subjects, and completion of CAS 3. A grade E in either TOK or the EE is a failing condition that can block the Diploma even with 24-plus points.
This is the part students miss. You can hit 24 and still not earn the Diploma if your distribution fails the rules. Check the conditions with your DP coordinator, not just the total.
Higher versus Standard Level
Higher Level goes deeper and is valued by universities for subjects related to your intended degree. Standard Level gives breadth. Most students take three Higher Level subjects aligned with their university plans, which keeps the workload sane while still signaling focus.
The hour difference is the practical reason. With about 240 hours at HL versus about 150 at SL, the HL syllabus covers more topics and expects more independent application 2. If a subject is central to your degree, taking it at HL shows preparation. If it is a contrast subject you enjoy but will not study further, SL protects your time for the subjects that matter more.
Internal Assessment and Final Exams
Most subjects combine internal assessment, marked by your teacher and moderated by the IB, with final external exams at the end of DP2. The weight of each varies by subject, but the pattern is consistent: steady work through the two years feeds the internal marks, and a focused revision block feeds the exam marks.
Do not ignore the internal assessment
Internal assessment is where the IB rewards consistent effort. A lab report, an oral, or a written commentary completed well before the exam period lifts your grade without a single exam hall. Students who treat it as minor often regret it when final exams do not go as planned.
Plan the exam block early
The final session packs several subjects close together. Build a revision calendar in DP2 that spreads subjects across the weeks, rather than cramming the night before each paper. The spaced review habit from earlier in this guide is what makes that calendar work.
Use your school's mock results
Mock exams exist to show gaps, not to grade you. Read the feedback, find the topics where you lost marks, and prioritize those in revision. A mock that exposes weak spots is more useful than one that flatters you.
A Study Method for the IB
The IB rewards steady work because deadlines arrive from several directions at once. A single week can hold a subject test, an EE checkpoint, and a CAS log due date.
Start the Extended Essay early
The 4,000 word essay is easiest when begun in DP1. Choose a question you can research with sources you can reach, and draft a section each month. A research question that is too broad becomes a year long struggle; a narrow one you can actually investigate becomes a manageable project.
Keep CAS current
CAS fails when left to the last term. Log activity as you go so the portfolio is evidence rich and the reflection is genuine. A small weekly habit avoids a stressful catch up and produces better reflections, because you remember the experience while it is fresh.
Rotate subjects with spaced review
With six subjects, nothing can be ignored for long. Build a weekly rotation so each subject gets attention and the Higher Level material stays sharp. Spaced review beats cramming before each exam, especially when several subjects test close together in the final session.
Common Misconceptions
- "The Diploma is just six hard courses." The core of TOK, EE, and CAS is half the identity of the programme and part of the score.
- "24 points means automatic pass." Distribution rules and the CAS and TOK/EE conditions can still block the award.
- "Higher Level is always better." Three HL subjects are normal, but four can overload you. Match the count to your degree plan and stamina.
- "CAS is a box to tick." Treat it as an 18 month habit, not a last term scramble, or the reflection quality suffers.
- "The EE is only writing." It is research design, source evaluation, and time management as much as prose.
Frequently Asked Questions
Is the IB Diploma harder than A-Levels?
It is different rather than simply harder. The IB asks for breadth across six subjects plus the core, while A-Levels allow deeper focus on three. The right fit depends on how you like to study.
Can I take the IB without a school?
The full Diploma is offered by authorised IB World Schools. Some components can be taken as certificates, but the complete Diploma requires an IB World School.
What score do universities want?
Requirements vary widely. Competitive courses may ask for 38 points or more with high Higher Level grades, while many universities accept lower totals. Check each institution's published entry criteria.
Does the Extended Essay earn points?
Yes, together with Theory of Knowledge it can add up to 3 points to the 45 total through the published matrix 1.
Is the IB recognised outside Europe?
Yes. The IB Diploma is accepted by universities in the UK, Europe, North America, and many other regions, often with published conversion tables. Recognition details differ by country and institution.
Where should I start tonight?
Open your subject syllabuses, pick one Higher Level subject, and sketch a monthly plan for the Extended Essay. Starting the EE question now is the single move that pays off most in DP2.
