IB Year 1: A Practical Guide to Starting the Diploma

Starting the IB Diploma is a significant jump from whatever came before. The first weeks can feel exciting, overwhelming, or both. This guide covers exactly what Year 1 looks like, which components you should start early, and how to build the habits that make Year 2 manageable rather than brutal.

IB Year 1 is the first of two years in the IB Diploma, when you learn content across all six subjects and begin the Extended Essay and CAS.

The key to IB Year 1 is not just keeping up: it is getting ahead on the Extended Essay, on CAS, on your notes, and on genuine understanding rather than surface memorisation. Students who treat Year 1 as a warm-up run into serious trouble when Year 2 brings coursework deadlines and exam revision at the same time.

What the IB Diploma actually requires

Before you can plan Year 1 sensibly, it helps to know exactly what you are working toward. The IB Diploma is scored out of 45 points:

• Six subjects (3 Higher Level, 3 Standard Level): each graded 1 to 7, giving a maximum of 42 points from subjects.
• Theory of Knowledge (TOK): assessed by an essay and an exhibition. Contributes up to 3 bonus points in combination with the Extended Essay.
• Extended Essay (EE): a 4,000-word independent research essay in a subject of your choice.
• Creativity, Activity, Service (CAS): ungraded, but you must complete it to receive the diploma. Missing the CAS requirement means no diploma regardless of your points.

The bonus 3 points from TOK and EE are the difference between a 39 and a 42, or a 42 and a 45. They are not minor. The full programme structure is set out on the IB's official diploma page.

Year 1 vs Year 2: the split most students misunderstand

Most students do not grasp this distinction until it is too late.

Year 1 is when you learn the content for all six subjects, register for CAS, and make your first real progress on the Extended Essay. The exams are still far away, which makes it tempting to treat Year 1 as a lower-stakes year. It is not.

Year 2 is when the deadlines converge: Internal Assessments in most subjects, the EE submission, the TOK essay, mock exams, and final exam revision all fall in the same calendar year. Students who coasted in Year 1 hit Year 2 carrying content gaps that are very hard to fill under that kind of time pressure.

Everything you learn in Year 1 is examined in Year 2. The two years are one programme, not two separate ones.

The three things to start in Year 1 (most students leave them too late)

1. The Extended Essay

The EE is a 4,000-word independent research essay. Most schools require it to be submitted in the autumn of Year 2. That sounds far away. It is not.

Writing a good EE requires choosing a subject and research question, reading widely and gathering sources or data, meeting your supervisor for three formal reflection sessions (a mandatory IB requirement), and drafting and revising the essay across multiple versions. Compressing that process into the first months of Year 2, while managing IAs and starting exam revision, is genuinely very difficult.

What to do in Year 1: decide your subject by the Christmas break, draft a research question by spring, and aim to have an outline or early draft done before Year 2 begins. Students who follow this approach consistently describe the EE as a manageable side project. Students who leave it to Year 2 describe it as a crisis.

The extended essay guide covers the full process in detail.

2. CAS registration and early activities

CAS requires you to document experiences across Creativity, Activity and Service, with reflective writing that shows genuine personal growth throughout the diploma. It is pass or fail, but failing it costs you the diploma entirely.

Register your CAS profile and begin your first activities and reflections from the start of Year 1. Do not treat CAS as a Year 2 admin task. The IB requires sustained engagement over the full two years, not a cluster of activities in the final term.

3. Your Internal Assessments

IAs vary by subject, but in most IB courses the final IA is submitted in Year 2. The research, data collection, fieldwork or coursework that goes into it typically begins in Year 1. Check your school's IA timelines for each subject and note when you need to have made meaningful progress. Starting late on an IA that requires primary research or lab work is very hard to recover from.

Read the IB Internal Assessment guide for an overview of what each subject's IA involves.

How to study the content in Year 1

IB subject content is substantial, especially at Higher Level. You will be expected to retain what you learn in Year 1 across the full two years until exams. This makes your choice of study method more important than it would be for a one-year course.

The research is clear on what actually works. A 2013 review by Dunlosky and colleagues, published in Psychological Science in the Public Interest, tested ten common study techniques and found that two consistently outperform the rest: active recall (testing yourself rather than re-reading) and spaced repetition (reviewing material at increasing intervals to counter the forgetting curve). For a two-year course where you need Year 1 content to still be solid in eighteen months, spaced repetition is not optional. It is the mechanism that makes long-term retention actually happen.

Practical steps for Year 1:

• After each lesson, write a brief summary from memory before looking at your notes. Even five minutes of this significantly improves retention compared to passive review.
• Use spaced repetition for key definitions, formulae, dates, case studies and vocabulary from the start of Year 1. If you build this habit in October, you will not be cramming the basics in April of Year 2.
• Use active recall on past-paper style questions early in Year 1. It reveals gaps while there is still plenty of time to address them.

Also read the official IB subject guide for each of your subjects. It is the definitive list of what can be examined, written by the IB itself. Students who study from the subject guide know exactly what they are working toward. Students who do not often revise content the exam will not test.

Managing six subjects at once

The IB requires you to be competent across six different subjects simultaneously. For most students, this is the hardest adjustment from their previous course.

You will almost certainly have subjects you find easier and subjects where you struggle. The temptation is to spend more revision time on the subjects you enjoy and to avoid the ones you find hard. This is the opposite of what improves your grade. Your most valuable study time is almost always spent on your weakest subjects and your weakest topics within each subject.

An IB revision timetable that gives proportional time to each subject, weighted toward areas of difficulty, is one of the most straightforward ways to improve your overall points total. The IB workload guide goes deeper into how to balance everything in practice.

This is also where managing your own studying becomes genuinely tiring. Deciding what to study each week, tracking what you have and have not covered across six subjects, and remembering which topics need reviewing is real overhead on top of the actual work. Most students end up spending time on whatever feels most urgent rather than whatever would most improve their grade.

This is the part where most students hit a wall, and it is worth knowing there is a tool that handles it. Root (roottutor.com) is an adaptive tutor and AI study manager built for the IB, designed by an IB student, that runs the system for you rather than being something you have to drive. It does not just hand you flashcards: it learns exactly what you find difficult, works out which explanations actually make sense to you, and automatically schedules what to study and when to revisit topics, so you are doing spaced repetition across your subjects without having to plan any of it. On the free plan you get 60 tutor messages a week across 2 active units, 2 exam-style practice tests per week with examiner-style per-question marking, and a revision mode that finds your weak areas and brings them back until they stick. If that sounds useful, here is a full breakdown of what Root does, or you can try it free with no card details.

What good habits actually look like in Year 1

In practice, Year 1 students who do well tend to share a handful of patterns:

• Weekly review sessions for each subject. Even short ones, kept up every week, maintain the spaced repetition that prevents Year 2 content catch-up.
• Organised notes from the very start. Trying to reorganise a year's worth of disorganised notes during Year 2 exam prep is a poor use of extremely limited time.
• Reading around your subjects. For humanities subjects in particular (History, Economics, Psychology), understanding ideas at a level deeper than the textbook produces noticeably better essay writing in exams.
• Asking for help early. IB teachers would much rather help a student who raises a difficulty in October of Year 1 than one who surfaces a content gap in March of Year 2. Do not wait until a problem becomes a crisis.

A realistic picture of the workload

For most students, the IB requires around 15 to 20 hours of independent study per week outside lessons. This is significantly more than most pre-IB programmes, and it takes a few months to adjust. The students who find Year 2 manageable are usually the ones who built this study volume gradually in Year 1, not the ones who tried to switch it on overnight when deadlines arrived.

The IB is demanding. But students who start early, use their time on the right things, and keep their coursework components moving steadily across two years find it genuinely achievable. The ones who struggle are usually the ones who treated Year 1 as a warm-up.

What to do right now

If you are in the early weeks of IB Year 1, the most valuable things you can do are:

1. Choose your Extended Essay subject and begin thinking about a research question.
2. Register your CAS profile and begin your first activities.
3. Get your study system in place: organised notes, regular review sessions, and active recall rather than re-reading.
4. Read the official IB subject guide for each of your six subjects so you know exactly what is examinable.

Year 2 will be busy regardless. Year 1 is where you decide whether busy becomes manageable or overwhelming.
