Kent usually only does the first 15 types as shown herehttp://www.elevenplusexams.co.uk/cd/
although i usually briefly cover 16 to 21 - often called the HIKNOS types as very occasionally one of them ahas popped up.
You can use Susan Daughtrey tests ( NOT the books) - they cover the additional 6 types , but are good for practice ..
make sure you buy the multiple choice test papers not standard version.
