If your May results landed below the grade your university offer needs, a November retake is often the fastest route back to the place you already earned. The IB runs two full examination sessions a year, May and November, and the November session exists precisely for students who want to lift one or two grades without repeating the whole two-year programme. It is a real, structured second chance, and thousands of students take it every year. The important thing is to decide quickly and calmly, because the registration window is short.

This guide explains how the November session actually works, what you can and cannot resit, the timeline that matters for your university place, and how retake preparation differs from first-time study. Retakes are won on the written papers, and you start from your May marks rather than from a blank page. Used well, that is a genuine advantage. Below is the complete picture, the sort of plan we build with students at 4S Academy every autumn.

How the November session works

The November session is a complete examination sitting held in October and November, with results released in early January. It mirrors the May session in every way that counts: the same syllabus, the same paper structure, the same grade boundaries and rigour. For students in the northern hemisphere it is usually described as a "retake" session, because most November candidates are resitting rather than taking the diploma for the first time.

You register as a retake candidate through the same school that entered you in May, working with your IB coordinator (DPC). You do not apply to the IB directly. If you have left school, or your school does not offer the November session, you will need to sit as a registered candidate at another IB World School that accepts external or transfer candidates. Sort this out early, because finding a centre can take longer than the revision itself.

Your January results are what you then send to universities. Most institutions, especially in the UK, Ireland, and across Europe, are used to receiving updated IB grades in January and will reconsider a place on the strength of them. This is exactly why the November session exists, so a single paper that went badly in May does not have to cost you a year.

What you can and cannot retake

Here is the part that saves the most stress: you almost never need to redo the whole diploma.

You may resit individual subjects. If your problem is one grade in one subject, you register for that single subject in November and leave everything else untouched. You can resit more than one subject if you need to, but you only sit the ones you choose. Everything you already passed stays exactly as it was.

Crucially, you keep your coursework and internal assessment marks. Your Internal Assessment (IA), your Extended Essay, your Theory of Knowledge essay and presentation, and any other coursework component carry forward automatically. You are not rewriting your Physics IA or your TOK essay. When you resit a subject in November, you are re-sitting the written papers only, and your existing coursework mark is folded back into the new subject grade. This is the single most important fact about retakes, and we will come back to what it means for your plan.

You can also choose to carry forward a subject grade you are happy with, or reattempt it if you think there is more available. In practice, most students resit one or two subjects, keep the rest, and lift their total points by the two or three they need for the offer.

Whether to redo the whole diploma is almost always the wrong question. Repeating everything means re-registering across the board, redoing coursework you have already passed, and gambling grades you have already secured. Unless your overall points are a long way short and several subjects are weak, a targeted one or two subject resit is faster, cheaper in effort, and far lower risk.

The registration timeline that matters

The timeline is tight, and missing it is the most common way students lose a retake they could have had.

  • Late June to early July: May results and the diploma are released. This is the moment to decide, honestly and quickly, whether a resit closes the gap to your offer.
  • July to early September: talk to your IB coordinator, confirm which subjects to enter, and if you are an external candidate, secure a school that will register you.
  • Around mid-September: registration for the November session typically closes. Treat this as a hard wall. Confirm the exact date with your coordinator, because it can vary slightly by school and region, and late entry is not something to rely on.
  • October to November: the examinations are sat.
  • Early January: results are released, and you send the updated grades to your universities.

The uncomfortable truth is that the decision window and the registration deadline both fall in the summer, when schools are quiet and coordinators are hard to reach. Do not wait for term to start. If you think you might resit, email your coordinator the week your results come out. If you are unsure of the exact closing date, the honest answer is "around mid-September, confirm with your coordinator," and confirming it should be your first action, not your last.

How retake prep is different from first-time study

First-time IB study is broad: two years, six subjects, coursework, and the core, all running at once. A retake is the opposite. It is narrow, deep, and short, and it should be planned that way.

Three things make it different:

You start from your May marks, not from scratch. You already sat these papers. Your Subject Report and, where available, your marked scripts or your teacher's feedback tell you precisely where the marks leaked. Maybe it was Paper 2 long questions under time pressure, or one topic you never truly locked down. Retake preparation begins with that diagnosis, not with reopening chapter one.

It is won on the written papers. Because your coursework is already banked, every hour you invest goes straight into exam technique and paper performance. That is a cleaner, more measurable target than first-time study ever offers. You are not managing an IA deadline or a TOK presentation at the same time. You are training for two or three specific papers, and nothing else.

Technique outweighs fresh content. Most retake students do not have a knowledge hole so much as an execution gap: timing, method marks, showing working, reading the command terms, using the calculator or the data booklet efficiently. The fastest gains come from timed past papers marked against the real markscheme, then closing each specific weakness. This is where focused one-to-one teaching pays for itself, because a specialist can look at your May performance and tell you the two or three changes that move a 5 to a 6, or a 6 to a 7.

A realistic 8 to 12 week plan

From a September registration to November papers you have roughly 8 to 12 weeks. Here is a structure that fits alongside university plans, a gap, or a first term elsewhere.

Weeks 1 to 2: diagnose. Read your Subject Report for each resit subject. Map your May marks against the paper components. Identify the specific topics and question types that lost marks. Build a syllabus checklist and rate every topic honestly as secure, shaky, or weak.

Weeks 3 to 6: rebuild the weak topics. Work only on the shaky and weak items. Relearn the method, then practise it on question banks by topic until it is automatic. Do not revise what you already know well, that time is wasted. For IB Maths this means drilling the exact question styles you dropped; for Physics it means the derivations, the data booklet, and the experimental questions that catch people out.

Weeks 7 to 10: full timed papers. Sit complete past papers under real conditions, to time, no notes. Mark them ruthlessly against the official markscheme. Every lost mark becomes a mini-lesson. This is the phase that builds the exam stamina and pacing that a single bad May paper usually exposed.

Weeks 11 to 12: polish and simulate. Sit final full mocks, refine timing, and rehearse the calm routine you will use on the day. Taper the intensity in the last few days so you arrive fresh, not frayed.

Adjust the ratios to your gap. With only eight weeks, compress the rebuild phase and start timed papers sooner. The one rule that does not bend: finish on timed, marked papers, because that is what the November grade actually measures.

If you want that plan built around your exact subjects, your May marks, and your offer, this is what our retake programme does.

Common mistakes to avoid

Deciding too late. The registration wall in mid-September is unforgiving. Students who wait until term starts to "think about it" often find the window has closed. Decide in July.

Revising what you already know. It feels productive to redo comfortable topics. It changes nothing. A retake is won by closing the specific gaps that cost you marks in May, not by rereading the whole course.

Ignoring the Subject Report and your May scripts. These are a marked map of exactly where you lost points. Skipping them means preparing blind and repeating the same errors in November.

Treating it like first-time study. You do not need two years of breadth. You need depth on a few papers. Trying to relearn everything from scratch wastes the short time you have.

Forgetting the coursework is banked. Some students panic about their IA or Extended Essay. Those marks carry forward. Your energy belongs on the written papers, full stop.

Working alone on technique. Content you can revise solo. Exam technique, pacing, and the precise reasons a 5 became a 6 are far harder to see in your own work. This is where a subject specialist earns their place.

Where 4S Academy fits

We prepare international students for November retakes online worldwide and in Barcelona, taught by a subject specialist rather than a rotating roster. We teach IB Maths (both Analysis and Approaches, AA, and Applications and Interpretation, AI) and IB Physics at Standard and Higher Level, and our retake work is built around one idea: read your May performance closely, then spend every hour on the changes that move your grade.

A retake is a short, focused campaign with a clear finish line. Handled well, it turns a disappointing January into an offer confirmed. If you are weighing it up, the best first step is a short conversation about your subjects, your marks, and whether a resit realistically closes your gap.
