How Pass Masters helps

English

Comprehension, vocabulary, spelling, punctuation and grammar practice that gets harder as your child improves, with step-by-step explanations.

Maths

Arithmetic, problem solving, fractions, ratio, geometry and data questions pitched to your child's year, from Year 3 up to early KS3 stretch work in Year 7.

Verbal reasoning

Codes, word links, missing letters, analogies and sequences in weekly topic islands, plus timed CAT4 and ISEB-style papers.

Non-verbal reasoning

Shape patterns, rotations, reflections, nets and matrices, drawn as clear diagrams so children learn to spot the rule.

Science

Pass Masters does not teach science content yet. Its reasoning practice still builds the careful reading and problem-solving that science papers reward.

ISEB-style timed tests

Full timed papers in the four Pre-Test areas so your child gets used to working at pace on screen before the real thing.

In topic practice and subject quizzes, Miss Obstein gives hints without giving away answers, then explains mistakes once your child has answered.

Suggested practice timeline

  1. Year 5: Strengthen core maths and English and introduce reasoning question types used in the ISEB Common Pre-Test.
  2. Year 6: Timed ISEB-style practice across English, maths, verbal and non-verbal reasoning ahead of the Pre-Test.
  3. Year 7: Early KS3 stretch work to keep skills sharp. For Year 8 Common Entrance or scholarship papers, your child will need extra subject study beyond Pass Masters.
