The London superselective tests covers maths, English, verbal reasoning and non-verbal reasoning. Most families start steady preparation in Year 4 or early Year 5, building accuracy first and speed later, then sit timed papers through the summer before the test, which usually takes place in September.

For English, read widely every day and practise comprehension, vocabulary, spelling, punctuation and grammar; selective tests reward precise word knowledge.
Verbal reasoning is a set of learnable question types, such as letter codes, hidden words and word analogies. Learning each type, then practising it against the clock, lifts scores quickly.
Non-verbal reasoning is about spotting patterns in shapes: rotations, reflections, sequences and matrices. Short, regular sessions work better than long ones.
