only just found this, you may have done the test by now.
i assume you will be taking the B test for airside roads and aprons.
its a fairly simple familiarisation excercise, then a 50 question multiple choice test, which you need to score 96% to pass.
the answers are mostly obvious, but as with all CAA based tests, the purpose of the question is not always clear. so just read the questions carefully, and you will be OK.
good luck.
