Each mock is auto-marked with an instant percentile so you can see how your child compares, plus indicative benchmarks for Independent schools (ISEB / CEM) grammar schools such as Highly selective independent and Selective independent.
Whizlo tracks readiness against well-known Independent schools (ISEB / CEM) selective schools including Highly selective independent, Selective independent, CEM-entry independent, with an indicative "aim for" percentage on each mock.
