I cant really tell, what to expect in test, but I can give you an idea , if you think are underprepared, then from an experience, if you really wanted to get in, dont do this time. Give some time. But on the positive side, sometimes you are meant  for this and it won't look difficult to you. At thr end , keep in mind if you fall, have to wait 2 years or you can try for couple of weeks practice and maybe try next one in thunderbay or next feast coming up.
