I have created my own database of practice material [including genuine exam papers] including the ‘Foundation Knowledge Checklists’ which is intended to get a child ‘rock solid’ on the basics required to pass the 11+.
I have Identified the common themes as part of the 11+ test, what the exam setters do not tell you e.g. if they mention a leap year they simply expect a child to know that this means February will have 29 days not 28 etc. They will not hand this information to the child on a ‘silver platter’ as I like to say! I am often amazed by what children do not know so ensure foundations are rock solid asap.
I have now been tutoring professionally since 2012 and now predominantly online since 2015 after word spread wider afield. I have also 'sat' hundreds of exam papers myself and my mantra is to combine 'speed with accuracy' at all times.
