Selection at FTE is not free. They simply pass the cost off to their students. Except only those who pass it and enrol pay and they are paying for those who fail it or don't join too! It's a bit more difficult and costly to get there, so they probably had to drop the up front fee to get enough people to come. In the end, they are still less expensive than Oat, so most people probably don't care if they are paying the cost of assessing those who failed, but don't kid yourself into thinking anything an FTO does is free!
