Im afraid my answer to that is definitely yes. They will take your money so try not to be fooled by anything. Obviously they won't let you on if you've not got the aptitude to have a good go, but at the same time they don't have any airlines to answer to. Quite a few can drop out if they can't cope. Passing the aptitude test only makes you feel like you're good enough to get on the course, which encourages you to hand over your money.
I haven't yet done my training, Im still considering where Im going to go, and Im also considering Oxford. A friend of mine is just finishing his course there now which is why I know a little about it. But as anyone else will tell you, they're money grabbers, however they are one of the most reputable schools around and the airlines seem to like their style.
Just make sure its you who is deciding where you're gonna train and don't let them just sell it to you, have a look at other places aswell before deciding.
