Most IB difficulty is structural rather than academic. Students are carrying subject content across a broad spread of subjects while producing substantial independent coursework, over two years, with internal assessment feeding the final result. The common failure is not a hard topic — it is a deadline collision that nobody planned for.
That means the useful help is often not subject teaching at all.
What the structure actually changes
Breadth is compulsory. Students carry a wide subject spread rather than specialising down to three or four. Dropping a subject you dislike is not available in the way it is on the A-Level track, so a weak area has to be managed rather than avoided.
Higher and standard levels differ in depth, and the combination a student chooses shapes their workload substantially. A poorly chosen higher-level subject is a two-year commitment.
Coursework runs alongside content. Internal assessments in individual subjects, an extended piece of independent research, and the theory-of-knowledge strand all demand sustained independent work at the same time as regular teaching continues.
Assessment is continuous. Work produced across the two years contributes to the final outcome, so a bad term is not fully recoverable by a strong finish in the way it can be under a purely terminal examination.
Writing is required nearly everywhere. Even the sciences demand structured written analysis, evaluation of method, and discussion of limitations. Students who are strong at content and weak at written analysis feel this across every subject at once.
Where students actually struggle
Coursework timing. Internal assessments and the extended research piece are open-ended, which means they expand to fill available time and then collide with everything else. This is the most common source of genuine crisis, and it is a planning problem.
Written analysis in the sciences. Designing an investigation, evaluating method, discussing limitations and uncertainty. Different from knowing the chemistry or the biology, and assessed separately.
Breadth under time pressure. Six subjects progressing simultaneously means no subject gets the concentrated attention a student might give it in a narrower programme. Students who work sequentially rather than in parallel struggle here regardless of ability.
Independent research skills. Framing a question that is answerable, scoping it sensibly, and sustaining it. Rarely taught explicitly and frequently the difference between a comfortable second year and a fraught one.
Language-and-literature analysis, where the demand is close reading and structured argument about texts rather than language accuracy — a distinction that catches out students with strong English.
Sorting the actual problem
Before arranging subject tuition, work out which of these applies. They need entirely different help.
Content gap in a specific subject → subject teaching. Straightforward, and the case where a subject tutor is the right purchase.
Written analysis and evaluation weakness → work on written technique, which transfers across subjects. Fixing it in one subject usually improves several.
Coursework and deadline management → planning support, not teaching. A tutor hired to teach chemistry will not fix an extended-essay timeline, and hiring one for that reason wastes both money and the student’s remaining hours.
Workload and prioritisation → the same, and adding tuition sessions to an already-full week makes it actively worse.
A large share of IB students who feel they need tuition in three subjects actually have one written- analysis problem and one scheduling problem.
What subject tuition is genuinely good for
Content gaps at higher level, where depth exceeds what a student can self-teach around.
Written analysis technique — investigation design, evaluation, limitations, discussion. The most transferable thing to buy, because it improves work across subjects rather than one.
Coursework feedback on structure, scope and argument, within whatever limits on assistance the programme sets. Confirm those limits before engaging anyone — what a tutor may and may not do on assessed coursework is defined by the programme and by the school, and getting it wrong is a serious problem rather than a minor one.
Examination technique in the final year, where command terms and answer structure are specific and learnable.
The coursework calendar is what actually needs managing
Because open-ended work expands to fill whatever time is available, the collisions are predictable — which means they are also preventable.
Map the deadlines across subjects at the start of the year, on one page. Each subject’s internal assessment has its own timeline, and they were designed independently. Nobody checks whether three of them land in the same fortnight; the student discovers that themselves, usually too late to do anything about it.
Front-load the choosing. For every piece of independent work, deciding what to do is the part that most often goes wrong and the part with the least visible progress. A student who settles a workable question early has removed the largest risk.
Set internal deadlines earlier than the real ones, with something concrete due at each — a question agreed, data collected, a first section drafted. Open-ended work without intermediate checkpoints is where terms disappear.
Treat the extended piece of research as a term-length project, not an essay. Students who approach it as something to write in the final weeks produce something that reads that way.
This is planning support, not teaching, and it is frequently the highest-value thing a family can arrange — but it should be recognised as what it is rather than bought as subject tuition.
Written analysis transfers across subjects
For students carrying difficulty in several subjects at once, this is the point worth acting on.
The demand that recurs across the IB — in the sciences, in the humanities, in the coursework — is structured written analysis: making a claim, supporting it, evaluating how strong the support is, and acknowledging what would undermine it. The subject changes; the shape does not.
A student weak in this is weak in it everywhere, which is why the pattern presents as “struggling in three subjects” and gets treated with three tutors.
Improving it once improves all of them. That makes it the most efficient purchase available, and the one families are least likely to identify, because the problem never announces itself as a writing problem — it announces itself as a chemistry problem, and separately as a history problem.
The diagnostic is straightforward: look at whether the student’s marks are lower on the extended, written parts of each subject than on the shorter, more factual parts. If that pattern holds across subjects, the common factor is the writing.
On timing
Because assessment is continuous and coursework is spread across two years, waiting until the final year is a worse strategy here than under a terminal examination system. Work already produced is already counted.
The corollary: the highest-value moment for support is usually earlier than families choose it — when a student is establishing how they will handle parallel demands, rather than when the deadlines have already collided.
Frequently asked questions
Is IB harder than A-Levels? Different rather than harder. IB is broader with more coursework and continuous assessment; A-Levels are narrower and more examination-weighted. Students who prefer depth often find A-Levels suit them; students who write well and organise well often find IB does.
My child is strong in science but struggling with IB science. Why? Most often written analysis — investigation design, evaluation, limitations — which is assessed separately from content knowledge and is a different skill.
Can a tutor help with internal assessment or the extended essay? Within defined limits, and those limits are set by the programme and the school. Establish them before engaging anyone; feedback on structure and scope is generally different from assistance with the work itself.
Should we get tuition for every subject that’s difficult? Usually not. Check first whether the common factor is written analysis or scheduling, in which case one intervention addresses several subjects and three tutors would address none of them.
When is the best time to start? Earlier than most families choose, because assessment is continuous. Support that establishes working method in the first year is worth more than remediation in the second.
