wahey..... back on topic....
i went for my assesment and out of 6, 3 of us passed, none of us that passed had ppl's but 1 guy did and he was rejected completely, not even asked back for a resit which i thought was harsh cos he was a really nice guy and am sure he passed the sim, and group tasks.
anyway OAA are not biased, not in my opinion anyway.
best of luck
