What it covers

The test is written for the start of DP1 of IB Maths AI SL. It covers the GCSE / MYP maths an AI SL course builds on, with more number, percentages and data: number, algebra, graphs, measurement, statistics and probability. Each question is tagged with the topic it tests, so the report maps straight onto the course:

Order of operations
Percentage decrease
Reverse percentages
Sharing in a ratio
Significant figures
Standard form
Laws of indices
Expanding brackets
Linear equations
Substituting into formulae
Simultaneous equations in context
Gradient of a line

How it works

20 questions, four options each, one mark per question, about 40 minutes. Calculator allowed.
Online or on paper, alone or with a class: how the baseline tests work, and the questions students and teachers ask.

Two sample questions

These are like the questions in the test, with different numbers. They are not in the test itself.

Sample 1 · Percentage increase

A concert ticket costs €64. The price increases by 25%. What is the new price?

$€80.00$
$€48.00$
$€16.00$
$€89.00$

Show the answer and working

Answer: A

Multiplier $1.25$ : $64 \times 1.25 = 80$ .

B is what you get if you changed in the wrong direction. C is what you get if you found 25% of the amount, not the new amount. D is what you get if you added 25 instead of 25%.

Sample 2 · Mean

Five students' journey times (minutes) are $14, 9, 17, 12, 8$ . What is the mean?

$15$
$60$
$12$
$9$

Show the answer and working

Answer: C

Add the values and divide by how many there are: $12$ .

A is what you get if you divided by one fewer than the number of values. B is what you get if you forgot to divide. D is what you get if you gave the range.

Questions students and teachers ask

How long does it take?

20 multiple-choice questions, about 40 minutes. A calculator is allowed. A teacher can set it as a timed test.

What does the result show?

The score, a topic-by-topic report with the weakest topics first, the common mistake behind each wrong answer, and links to practise each weak topic. It shows where a student is starting from; it is not a grade prediction.
