Pre-Quest is an online platform designed by teachers to prepare for the ISEB CPT, GL and CAT4 tests

Pre-Quest is an online platform designed by teachers to prepare for the ISEB CPT and CAT4 tests.

In 2019, we designed Pre-Quest for Brandon students in Hong Kong. We have hundreds of Y4 and Y5 pupils who prepare for the ISEB Common Pretest and CAT4 assessments.Our tutors, who are teaching ISEB pre-test skills daily, have created our questions. We use Pre-Quest in our classes. Now, we are opening up the programme so more students can share our knowledge.

We know Pre-Quest works!  Each year, our students win interviews at selective schools including: Eton, Westminster, Winchester, Benenden, Marlborough, and Wellington. Our CAT4 students have excelled in Wycombe, Cheltenham Ladies, and GSIS assessments.

Pre-Quest succeeds by breaking down each topic. Students learn skills and practice a myriad of question types. You get to see which type of questions you have mastered and tips helps explain new question types. A link to Brandon allows you to book a tutor if your child needs a bit of extra help.

You won’t need to pay extra for tests or updates; one package includes all you need.

Questions from Pre-Quest parents

Do I need to buy add ons?

No. We use Pre-Quest daily in our tutorial schools and teachers are constantly adding new questions as tests evolve (so, we have just added poetry to reflect 2023 tests); at no additional cost to you.

Does it get harder as I get questions right?

Yes. Our adaptive system is developed to genuinely reflect progress and to ensure that students are given support when needed. Adaptive questions help to build confidence and to stretch!

Can I save tests and exercises?

Yes. Our tests use a mix random of questions from extensive databases allowing you to re-take with confidence knowing that you will be trying new challenges.

How do I know which questions have been mastered?

Our ISEB CPT questions are divided into types so you can see which styles have been mastered and where your child may need more practice.

How does it work?

We believe in drilling – practice, practice, practice.

What about parents?

You will able to see results on your dashboard or via an email reports. All tests are saved and you can see what question types your child has mastered. You can also book tutorial sessions with our online experts (extra cost)

What is the ISEB CPT – Common Pre-test? What is tested?

What is the ISEB CPT?

The ISEB Common Pre-test (CPT) is an online test used in admissions for most UK independent schools.

Since 2005, Brandon has been preparing students for entry to UK independent schools.For the ISEB CPT, Brandon created their own online platform to prepare for the assessment. We have also added in many of our own cunning designs so our students are ready for all challenges!

Our aim is to find and fill in the gaps in our students’ knowledge. So you can prepare in advance, each unit in PreQuest splits into three different levels. Students can choose to work through each stage or challenge themselves.

The ISEB Common Pretest covers four principal areas, all of which are tested with multiple choice questions:

  • Non-verbal reasoning (solving problems using diagrams and patterns)
  • Verbal reasoning (problems working with words and language)
  • Mathematics (working with numbers, value and sequences)
  • English (grammar, vocabulary and comprehension which can include fiction, non-fiction and poetry)
