How we make and check our questions

A practice question is only useful if it is clear, fair and has one right answer. This page explains how we try to make sure Onze+ questions meet that standard, including where we use AI.

Where the questions come from

Questions are written in the style of the GL Assessment 11+ papers for Maths, English, Verbal Reasoning and Non-Verbal Reasoning. They are original material. We do not copy past papers.

Many questions are built from templates, so a type such as letter codes or cube nets can be practised many times with fresh examples. We use AI tools to help draft questions and passages, and we do not publish a question just because a tool wrote it.

How we check them

• Automated checks confirm the basics: every question has exactly one correct answer, the options are different from each other, and the correct answer is not given away by being much longer than the others.
• Where the answer can be worked out by a program, such as arithmetic, codes and cube nets, the program solves the question independently and the result must match the answer we stored.
• A second review pass checks the question and its answer. For many English and reasoning questions this includes solving the question blind, without seeing the stored answer. Where the review disagrees with the stored answer, or finds the question unclear, we fix or remove it.

Explanations and the AI guide

English, Verbal Reasoning and Non-Verbal Reasoning questions come with a written explanation, so a child can see why an answer is right.

In lessons, when a child gets an answer wrong, they can ask the app's AI guide for a hint, an explanation or a harder challenge. These replies are generated by an AI model at that moment, so unlike the written questions they are not reviewed in advance, and they can occasionally be wrong. If the guide is unavailable, the app shows the written explanation instead.

If you spot a mistake

If you are reviewing your child's mock or assignment in the Onze+ app, use the Report question button under the question. Choose what looks wrong, add a note if you like, and send it. We receive the question, your child's answer to it and your note so we can check it, and it is not shown to other families. Reports come from parents, not from children.

Next to the question you will see what happened: reported, corrected, or checked and the answer shown is right. If a question is wrong we fix it or withdraw it.

If you are not in the app, or it is about something else, email [email protected] with the question and what looks wrong.

What this does not mean

Checking questions carefully does not make Onze+ an official source, and practice cannot promise a score or a school place. Formats differ between schools, so use our school finder to see what your target schools test. Read more about Onze+.
