But to be honest I must say at this point that when I marked and counted the words that I would have to look up, I came to the amount of 186 out of the 400.So if this test were really testing one's knowledge of English, I think it would have to be doubted.

How can I have 136 good answers (meaning I would by that have understood 272 words rightly) when I must look up 182 words I do not know? 272 + 182 = 454

(many words I guessed through French and Italian )

Of course it's useful. I'm going to learn 182 new words.
