What is the difference between tests A,B,C and D?

Chuckra Educational has four unique sets (A, B, C, D) of mock exam papers each year, so your child can attend a maximum of four Chuckra 11+ Mock Exam Days. Each set of papers includes English & Verbal Reasoning, Numerical & Non-verbal Reasoning. It does not matter in which order these papers are sat as all four sets are similar in difficulty.
