IB Revision Platform Costs: What Examiners Add to STEM Plans
Most IB revision platforms bill monthly, annually, per subject or as a full-course fee, so the real cost depends on how many subjects you study and which features sit inside each plan. For IB sciences and maths, we believe our All-Access and Per-Subject plans are the best value for money, because examiner-authored materials and integrated analytics come as standard.
TL;DR:
- Compare plans by dividing the total fee by months covered, and check auto renewal, trial length, card requirements, and refund terms before committing.
- The $9 monthly per subject plan suits one course, while the $19 all access plan may cost less across several subjects; calculate both totals first.
- Before paying, verify current syllabus alignment, examiner authorship, and question style against official IB sample papers, then confirm whether mocks or marked scripts cost extra.
- Teachers should compare school licence fees per student and check seat limits, reporting tools, group discounts, and any extra charges for additional accounts.

How do IB revision platforms price their subscriptions?
Before you compare headline prices, it helps to know the shapes that prices come in. Almost every platform you meet will use one or more of these:
- Monthly subscriptions: the most flexible option and the most expensive per month. Good for a short push before mocks or a single exam session.
- Annual or longer plans: usually cheaper per month, but you pay more upfront and commit for the whole period. Check whether the plan auto-renews and whether you are reminded before it does.
- Per-subject pricing: you pay for one subject at a time. This suits a student who needs support in a single course, but the total can climb quickly once a second or third subject is added.
- Full-course access: a longer plan covering the whole two-year diploma, often designed so you pay once and revise throughout.
- School licences: multi-seat pricing for classes or departments, usually with teacher reporting and sometimes group discounts.
Trials and guarantees change the effective cost more than most people expect. A free trial lets you test the question quality and the platform’s layout before spending anything, while a money-back window protects you if the content does not fit your course. Always read the terms: how long the trial lasts, whether a card is needed upfront, and how refunds are handled.
Billing practices also vary. Look for auto-renewal rules, whether a mid-term upgrade is prorated, and how educator accounts are set up and charged. Reading these details takes a little time and can prevent a surprise charge later.
User reviews give useful context on real-world experience too. Trustpilot reviews for revision platforms show mixed student satisfaction, which is a reminder that price alone never tells you whether a platform suits the way you study.
What do you get at different price points?
Price tiers tend to follow features, so it is worth asking what you are actually buying. Higher tiers on most platforms usually include:
- Extensive question banks: exam-style questions sorted by topic and difficulty, which is the heart of effective revision.
- Full mock exams: timed papers that mirror the structure of the real assessment.
- Animated, examiner-led videos: short explanations that break down tricky concepts.
- Examiner mark schemes: the marking logic behind each answer, so you learn how marks are really awarded.
- Integrated progress analytics: dashboards showing which topics are strong and which need work.
- Custom test builders: the ability to generate a test from the topics you choose.
Not all of these carry equal weight. If you are aiming for a top score, the features that move the needle are exam-style questions, examiner-authored materials and analytics that tell you where to spend your next hour. Flashcards and mobile apps are convenient, and mobile access is common: platforms publish listings on the Apple App Store and Google Play, for example. But convenience should not be the reason you pay more.
For science and maths students in particular, integrated analytics and examiner-authored content are where a paid plan earns its fee. A question bank without feedback tells you whether an answer was right. A question bank joined to analytics tells you why your marks are slipping on a certain topic, and that is the difference between busy revision and effective revision. This is the thinking behind our platform: every resource links to the next, from notes to questions to mocks to performance insights, so nothing sits in isolation.
Pro Tip: Before paying for any plan, write down the things that will most improve your next grade, such as timed papers, mark scheme practice or topic tracking, and check that each one is included at the price you are looking at.
How should you compare plans before you buy?
A good comparison starts with your own situation, not the platform’s marketing. Work through these questions in order:
- Is the plan per-subject or all-access? Multiply the per-subject price by the number of subjects you need, then compare it with the all-access price. Which option is cheaper depends on the number of subjects you need.
- How long does the plan last, and what is the monthly equivalent? Divide the total fee by the months covered so you can compare a monthly plan with an annual one fairly.
- Is the content current? Check the platform states alignment with the latest IBO curriculum updates. Content written for an older syllabus can send you down the wrong path.
- Does it reflect real exam material? Compare its questions with the official IB sample exam papers for the style, command terms and mark allocation.
- Who wrote the content? Look for named examiners or experienced IB educators. Authorship is one of the strongest signals of quality.
- What are the trial length and refund terms? A generous trial lets you judge the platform properly, and a clear refund policy lowers your risk.
- For teachers: what do school licences include? Ask about seat limits, group discounts, teacher reporting and whether student data can be tracked across a class.
- Are there extra charges? Confirm whether mock exams, marked scripts or extra subject packs cost more.
If you want to see what a well-built practice routine looks like before choosing, our IB exam-style questions practice workflow walks through it step by step. It is a useful yardstick for what any paid plan should support.
How do you work out the real cost? Pricing scenarios and quick maths
Two simple formulas make every offer comparable:
- Monthly equivalent = total fee ÷ months covered
- Cost per subject = total fee ÷ number of subjects
Here are three worked examples. The figures are illustrative placeholders, not real prices, so swap in the numbers from any plan you are considering.
- Single-subject student: compare the total fee for an annual plan with its monthly equivalent, then weigh any savings against the longer commitment.
- Multi-subject student: multiply the per-subject fee by the number of subjects needed, then compare the total with the all-access price. The better value depends on the plans and subjects involved.
- Small school licence: compare the total fee with the number of seats and the licence period to work out the cost per student.
Watch for hidden or add-on costs. Extra mock exams, additional teacher seats, marked scripts and separate subject packs can each push the final bill higher than the headline price suggested. If a platform does not list these clearly, ask before you buy. For parents planning the final stretch, our examiner-led parent checklist for exam preparation shows how short-term value should be judged.
Why can you trust our value claims?
Price should reflect what a platform can prove, not what it promises. Our materials are written by actual IB examiners and experienced educators, our resources are aligned to the current syllabus, and our focus stays firmly on IB sciences and IB maths. Alignment with the official specimen papers and curriculum updates published by the IBO is what turns a question bank into reliable exam preparation.
Examiner authorship and curriculum alignment are the two credentials that most justify a higher price, because they decide whether practice matches what you will meet in the exam hall.
When a platform’s sticker price looks high, check those credentials first. A slightly higher fee for examiner-written, syllabus-aligned content with built-in analytics usually costs less in wasted revision time than a cheap plan that misses the mark. For a closer look at how we approach practice, see our IB question bank guide for science.
Where do our pricing options offer the best value?
We built our plans so you can match the cost to your needs, and we believe examiner-authored content with integrated analytics makes Tiber Tutor the best offering for the money in IB sciences and maths.
- All-Access Plan: $19 per month, ideal if you study several sciences or maths.
- Per-Subject Plan: $9 per month for a single subject, a sensible fit when you only need one course covered. Check our pricing page for current trial details.

Who benefits most from paying for a revision platform?
I think the answer comes down to your goal. A top-score aspirant gets the most from an all-access plan, because examiner mark schemes and analytics are what separate a 6 from a 7. A consolidation student with one weak subject is usually well served by a per-subject plan. A teacher running a class should look at school licences for the reporting tools. Free resources can cover the basics, but the value of examiner-authored feedback is hard to replace, so weigh budget, subject count and that feedback together.
