PreIB Bridging Programme · Included with every plan · 7 days free

Worried about starting the IB?

Most students walk into DP1 Maths in September feeling behind before they've begun. The IB assumes you've already mastered a chunk of your GCSE / iGCSE / MYP5 content — and it doesn't stop to reteach it. The 6-week PreIB Bridging Programme covers it — worked examples, practice questions, end-of-week self-marked assessments and a live IB-readiness bar.

Included with every plan · 7 days free. New accounts get a week of full access, no card needed.

Included with every plan · 7 days free PreIB comes with Pro, alongside all four DP courses, and the free 7-day trial includes it. Schools: PreIB is included in Pro and Platinum school licences. The €20 summer offer closed on 28 August 2026.

Want to be prepared for success?

The PreIB Bridging Programme tackles the four most common gaps DP1 students report in their first month.

1

Algebra you thought you knew

Quadratics, indices, straight lines. In DP1 they come at speed with no revision. Get fluent now.

2

Your CG50 is a black box

SL AI and HL AI students, this is you. Learn every menu you'll use before you're graded on it.

3

Problem-solving under time

The IB rewards mathematical thinking, not memorised methods. Practise the mindset now.

4

Written maths & notation

IB expects a specific style of workings — set out logically, with justified steps. You'll get feedback on yours.

Not sure which stream?

3 quick questions — get your best-fit stream

This takes 15 seconds. We'll show which of the four PreIB courses your answers point to — and you can still browse all four afterwards.

What's in the programme

Practice for every stream

Bridging questions, each with a worked solution written by an IB Maths teacher.

Flashcards that teach the why

Spaced-repetition cards for each stream. Every formula, definition and method is paired with the reasoning behind it — build understanding, not just recognition.

Topic-by-topic notes

Concise refreshers — designed to be read in 10 minutes, not 10 hours.

Progress bar + mastery

Track your progress topic-by-topic. See exactly where you're strong or weak.

3 diagnostic tests

Easy, medium and hard — take them in order to prove you're ready for the DP.

Free preview

No card required. See what's inside before you decide.

Who is the PreIB Bridging Programme for?

Students starting the IB Diploma in September who want to arrive fluent in the pre-IB skills their DP1 Maths teacher will assume they already have. Works whether you're taking SL AI, SL AA, HL AI or HL AA. It runs across all 4 streams.

How much does the PreIB Bridging Programme cost?

PreIB is included with Pro (€99 a year or €12 a month; compare the plans). New accounts get 7 days of full access free, including PreIB, with no card needed. Schools get PreIB with a Pro or Platinum school licence. The €20 summer offer closed on 28 August 2026.

Which PreIB stream should I choose?

Take the 15-second router quiz at the top of the page — three quick questions on your preferences, target university subject and algebra confidence route you to the best-fit stream. You can still browse all four afterwards.

What's inside the Bridging Programme for each stream?

Worked examples, practice and a short weekly assessment for each of the 6 weeks, plus warm-up questions, flashcards and diagnostic tests (easy, medium and hard).

Is any of it free?

Yes. A preview of every stream is free without an account, Unit 0 is free for everyone, and new accounts get 7 days of full access to PreIB and all four DP courses.

Is there a difference between AI and AA?

AI (Applications & Interpretation) leans on the Casio CG50 calculator, real-world modelling and statistics. AA (Analysis & Approaches) focuses on algebraic fluency, exact-form answers and analytical techniques. PreIB gives you a stream-tailored version of both.
