How to retake IB exams as a private candidate
Retaking IB exams is usually not the confusing part. The difficult part is finding a school that can register you, making sure your subjects and session are possible, and leaving enough time for paperwork before the deadline. This guide walks through the process in the order students actually face it.
Five checkpoints from a target grade to exam day
- Define the outcome: record the exact diploma or university condition, not just “more points”.
- Check feasibility: confirm subject, level, syllabus and existing coursework with the coordinator.
- Prepare the request: match your name, date of birth and previous candidate details to your official documents.
- Confirm entry: distinguish a school's offer to host you from completed IB registration.
- Plan every paper: confirm venue, local start times, equipment and travel before exam day.
For two selected subjects, the IBretake EUR calculation is 150 + (2 × 800) = EUR 1,750. This is a budget input, not proof that the proposed academic route is viable. A subject may involve more than one paper; the selected subject count is not a paper count.
Start with the diploma-score checks, gather the registration documents, then use the 12-week study plan. Keep the current status of each checkpoint beside its supporting document. That lets you identify the next unfinished action instead of restarting the entire search every time you receive an email.
Who Can Retake IB Exams?
Anyone who has previously been registered for the IB Diploma Programme, either as a full Diploma candidate or as a Course (certificate) candidate, is eligible to retake. You don't need to have completed your Diploma to retake individual subjects.
Common reasons students retake:
- Missed the Diploma by 1 to 3 points, Retaking your weakest subject can push you over the 24 point threshold
- University conditional offer, Your offer requires a 6 in Chemistry but you got a 5
- Career requirements, Some professional programmes require specific grades
- Personal satisfaction, You know you can do better
Step by Step: How to Retake IB Exams
Step 1: Decide Which Subjects to Retake
Look at your results breakdown. Focus on exam subjects where:
- You were close to the next grade boundary (use our Grade Boundaries Calculator to check)
- You had a bad exam day but your underlying subject knowledge is strong
- You have time to actually prepare and improve
Step 2: Choose Your Exam Session
The IB runs two exam sessions each year:
- May session, Exams in late April / May. Results in early July.
- November session, Exams in late October / November. Results are released from mid December, with candidate access staggered by time zone.
Not all subjects are available in both sessions, and not all schools offer both. The May session has significantly more availability worldwide.
Step 3: Start One Search Request
This is usually the hardest part. With IBretake, you choose your countries and selected subjects once. Your request becomes active only after IBretake confirms receipt of payment; it then contacts eligible coordinators in the selected countries. You need an IB World School that:
- Offers the Diploma Programme
- Is willing to register external retake candidates
- Offers your specific subjects at the right level (HL/SL)
- Can host your selected subjects and session
You do not need to retake at your original school. Any IB World School that accepts you can register you for the exam. School names stay private until a school accepts the request.
Start one search and let IBretake contact eligible coordinators.
Start Your Retake Search →Step 4: Track Your Case
After checkout, your student dashboard shows your case number and search status. IBretake updates you there and by email if your request changes. Refunds open 10 calendar days after IBretake admin confirms successful payment processing, provided no school has accepted you. School acceptance completes the placement-search service and ends contractual refund eligibility.
Once a school accepts you, the final registration process may involve:
- Providing your previous IB candidate details (candidate number, session, subjects)
- Providing documents requested by the accepted school
- Paying the school's administration fee and IB assessment fees confirmed by the school
- The school registers you through IBIS (the IB's system)
For a full breakdown of costs, see the IBretake Cost Guide.
Step 5: Prepare and Sit the Exam
You'll sit the exam at the school's exam centre under the IB requirements for your new session. Confirm the current syllabus, paper structure, exam zone and reporting time with your coordinator; these may differ from your first sitting.
Internal Assessment and Coursework
IBretake searches are for exam hosting placements. They do not include new IA work, coursework supervision, oral preparation, tutoring, or coursework submission. If your retake depends on carrying forward an existing IA mark or handling any coursework component, confirm that directly with your previous school or the accepting IB coordinator before relying on the placement.
Key IB Rules for Retake Candidates
- No limit on retakes, You can retake a subject as many times as you want across different sessions
- Best grade used, For Diploma calculations, your best result is typically used
- Change level, Confirm registration, coursework and diploma requirements with the coordinator before changing HL/SL.
- Full fees apply, Each retake is treated as a new registration with full fees
- Different subject, Do not assume that a new course automatically replaces a previous result; get the proposed route approved by the coordinator.
For the full official policy, see the summary of the IB's official retake rules.
Registration Deadlines
Ask the host school for its exact acceptance, document, cleared-payment and IB entry cutoffs for your candidate category. Do not treat a generic October or April date as permission to register. Any late-entry route and charges need explicit confirmation.

How Much Does It Cost?
For students using IBretake, the platform price is fixed at EUR 150 registration plus EUR 800 for every exam, with no multi-exam discount. Checkout converts that formula to the selected currency where applicable. Non-platform costs to plan separately may include:
