My advice would be to post your query in the location specific thread. That way you will receive advice from parents who have experience in your area.
I am in Lincs and we also have NFER papers for VR and NVR. The work I did with my son was based almost entirely around the Susan Daughtry books as they were recommended to us by a member of staff in our local book store as being appropriate to the tests, and the material of choice by the local tutors.
My Son ( and I ) found the books very easy to understand and enabled practice in all question types and highlighted any problem areas for us to pay closer attention to.
My son passed and has been offered a place at the Grammer he wanted, so we have found they definatly worked for us. However, as i said before I would seek advice from those with experience in your area to be sure.
Hope this helps in some way
