No one knows what vocab is going to turn up.
My only suggestions is to keep reading out loud making note of ALL unknown vocab. You have the compound word list, do you have the Important Word list, found in the same section? The list is not the be all and end all, just a starter. The flas card system [ explained in the download] is ONE way of improving vocab.

In addition its always a good idea to use more advanced words in your every day language.
And, of course, one of my favourites......Scrabble....allowing the use of a dictionary.
Vocab is ALWAYS the problem with the Bucks VR test, I would be a millionaire if I could wave a magic wand.........enabling me to find the perfect solution.....
