The problem PreIB solves
Students who did well at GCSE, IGCSE or MYP often find DP1 maths harder than they expected. The DP assumes the earlier algebra is fluent, and it marks the method as well as the answer. PreIB is a short bridge: it rebuilds those foundations and gets you used to setting out working the way DP mark schemes reward.
What's in it
- A three-question quiz that suggests a stream: SL AI, SL AA, HL AI or HL AA. You can still look at all four.
- A six-week programme for each stream: worked examples, practice questions with worked solutions, a self-marked assessment at the end of each week and a readiness bar that shows your progress.
- Flashcards and short topic notes for each stream.
The AI streams lean on calculator fluency and modelling; the AA streams lean on algebra. HL streams assume a top IGCSE or GCSE grade; SL streams start a little lower.
How to get it
PreIB comes with IB Maths Pro (€12 a month or €99 a year), alongside all four DP courses. Schools get it with both school plans, School and School Unlimited.
You can start free. A free account needs no card and includes 7 days of full access, PreIB included. Without signing up you can try five PreIB questions and Unit 0, the prior-knowledge unit, which is free for everyone.
When it helps, and when it doesn't
It helps most in the summer before DP1 or in the first weeks of term, when gaps are still small. If you have already started DP1 and a topic keeps tripping you up, use the PreIB stream for your course to patch that gap, then go back to the course units.
If you are already comfortable with DP1 practice questions, you don't need it: go straight to your course.
Does PreIB guarantee a 7? No, nothing does. It gets the foundations in place; what happens in DP1 is still down to you, your teacher and your school.
A six-week bridge from GCSE, IGCSE or MYP into DP1 maths, in four streams. It comes with IB Maths Pro, and every new account gets 7 days of full access free.
