I'm hoping for some advice!
DC (13, currently in year 9) is due to sit a CAT4 test to transfer to another (selective) school for year 10.
She is bright, but has slow processing speed, possibly an unusual type of dyslexia. This particularly affects her reading speed and her maths. At school she normally get 25% extra time in assessments.
The new school asks for overall 120 in CAT, which should be attainable (she got well over 120 overall in Year 5, though in quite relaxed circumstances). I think however they also want 120 specifically in the numerical section, which is more of a problem. For example, in year 5 she scored something like 125 for non-verbal, 131 for verbal, but only 113 in numerical. Numerical reasoning takes a lot of time for her. (She's perfectly good at Maths though, perhaps not top 5% but comfortably in set 1 in her current non-selective school, scoring over 80% for the end of year Year 8 assessment).
My question is, how do we prepare for CAT testing, given that we are going to have to seriously work on speed? How much time will we need to prepare (in total and per week), how many practice papers, where do we get them from? If anyone has done this before, please let me know how you tackled it!
