verbal reasoning - 21 types?

[bexley mum 2]

Are there 21 types of of questions in bexley verbal reasoning and are they all used in the 4 nfer test papersthat you can buy? My child and I have just worked our way through the IPS verbal reasoning book that explains how to do them but are unsure if all types have been covered for the Bexley tests. The book was really helpful but still having a few problems with the similarities questions.
