Review: Ok - Ok
Review: Second time buyer （my top choice for 11+ prep.） - I used these for my older son's 11+ exam and they worked so well that I just bought the same one for my younger son. The exercises are well-structured and really help build the speed and accuracy needed for the test. This is the most useful practice set I've found. Definitely recommend to other parents!
