Athey or Alpha verbal reasoning for the Essex exams?

[Manana]

I've seen the brilliant post on here listing the VR books/papers by difficulty, but I wondered where the Athey verbal reasoning or the Alpha (Elizabeth Bell) books would be placed on that list? Would anyone who has used them be able to make a judgement call for me!? Or, if you don't use them for whatever reason, that would be useful to know, too!

Thank you
