The year that sets the first step
The gap between a 5 and a 7 is almost never intelligence, and it is rarely effort. It is consistency, practising the right things, and knowing honestly where you stand. Those are the parts a student is least able to manage alone, in the year they have least time.
The problem is rarely the maths
IBDP is demanding enough on its own.
Six subjects, the Internal Assessment, the Extended Essay, CAS. Then, in the second year, university applications, predicted-grade exams and — for anyone applying to a selective course — an admissions test, all landing between September and November.
Most students meet that by working harder in the autumn. It is the natural response and the least effective one, because by then everything has already collided. Something gets dropped, and it is usually whatever has the latest deadline.
The families who come through it calmly are not the ones who found extra hours. They are the ones who spread the same work across a longer runway, because somebody was looking at the whole calendar in advance.
What actually separates a 5 from a 7
Four things, in our experience of teaching the Diploma. None of them is a topic you can look up, which is exactly why they are hard to fix alone.
Consistency
Strong in bursts. Good marks on the topics they enjoy, visible dips on the ones they do not, and a wide gap between a good week and a bad one.
Steady across all five topics and across both years. Not spectacular on their best day — reliable on their worst. Consistency is the single clearest difference.
A plan that runs across both years rather than term by term, so the dips get caught while there is still time to fix them. Consistency is a scheduling problem before it is a mathematics problem.
What they practise
Works through the textbook, gets most questions out, and reads that as being ready. The book is written to teach a topic, not to examine it.
Works through past papers, filtered to the subtopics that are actually weak. Knows the difference between a question they can do and a question set the way the examiner sets it.
A question bank filtered to the subtopics a student is actually weak at, drawn from real exam-style material rather than the next exercise in the book.
Knowing where they stand
A general sense of having covered a topic, chapter by chapter.
Can say precisely what is done, what is left, what is solid and what is shaky — by subtopic, not by chapter. That list is what revision is planned around.
Proficiency tracked at subtopic level, not chapter level — so at any point we can say what is done, what is left, and what is shaky. Parents see the same picture we do.
How they handle the autumn
Lets September to November collect everything at once: applications, predicted-grade exams, admissions tests. Something gets dropped, usually whatever has the latest deadline.
Plans backwards from those deadlines months earlier, so the same work is spread rather than stacked. The pressure curve is flattened on purpose.
The autumn mapped backwards from the real deadlines — the IA, the mocks, any admissions test — before September, not during it.
What a selective place actually buys
Less than you are told. And more than you think.
It is worth being straight about this, because the usual version is overstated. Economists have compared students who were admitted to the same selective universities but chose to attend different ones — which strips out the ambition and ability that got them admitted in the first place. On that comparison the earnings advantage of the more selective place is close to zero. Most of the premium you read about is the kind of student who gets in, not the institution.
Two findings survive that correction, and they are the ones that matter to a family aiming at a selective course.
- The effect on average earnings is small — but the effect at the top is not. Attending a highly selective university raises the odds of reaching the top 1% of earnings by around 60%, nearly doubles the chance of attending an elite graduate school, and roughly triples the chance of working at a prestigious firm.
- The gains are largest for students without family advantage. For students whose parents did not attend university, the return to a selective place stays large even after the correction above.
- In the UK, graduates of Russell Group universities earn around 10–13% more than graduates of other institutions with similar backgrounds and prior attainment, rising to 14% or more for the top ten.
So a selective place is not a guarantee of a higher salary. What it changes is access — to the firms, the graduate schools and the top of the earnings distribution that are hard to reach any other way. That is what the two years of the Diploma are competing for, and it is why the difference between a 5 and a 7 is worth planning for rather than hoping for.

Questions parents ask
My child is already scoring a 5 or 6. Is a tutor really necessary?
That is exactly the band where guidance changes the most. Going from a 3 to a 5 is usually about filling content gaps, which a diligent student can do alone. Going from a 5 to a 7 is rarely about content — it is about consistency across all five topics, practising the right questions rather than more questions, and knowing precisely which subtopics are still shaky. Those are hard to see from the inside.
Is it not just about doing more hours?
More hours is the most common response and the least efficient one. A student who works through the textbook for three hours has often practised what they can already do. The same three hours spent on the subtopics that are actually weak, in the style the examiner sets, moves the grade further. Better planning usually means fewer hours, not more.
What does an expert see that a student or parent cannot?
Mainly three things: which mistakes are one-off slips and which are a misunderstanding that will recur, which topics look covered but will not hold under exam conditions, and how to sequence work around the IB calendar so nothing collides. All three come from having watched the same syllabus play out across many students rather than one.
Does going to a more selective university actually matter?
Less than most people assume for average earnings, and more than most people assume at the top. Research that compares students admitted to the same selective universities but attending different ones finds little difference in typical earnings — most of the apparent premium is the kind of student who gets in. But attending a highly selective university substantially raises the odds of the top-tail outcomes: the top 1% of earnings, elite graduate schools and prestigious firms. The gains are largest for students without family connections to those institutions.
Do you teach 1-on-1 or in groups?
Both. Sessions are either 1-on-1 or in a batch capped at five students, and everything is online. The batch format works well when students are at a similar stage; 1-on-1 suits a student with a specific set of gaps to close or a tight deadline.
