Absolutely agree with veetwo about the suspicion raised by the two posts. And also as veetwo said it is very important to get the statistics from them for the last year and if they hesitate to provide them, it should be enough to reconsider the option of studying there and apply for something like OAA.
As I see FTEJerez is becoming now the school for sponsored students (at least now, since there are not many sponsorships going on at the moment) and it raises doubts in me about wether to choose this school. Although at our University we had presentation whereas they mensioned that they have a queue of students to whom they are trying to provide a job. Also I received some positive response from FTEJerez grads, although they graduated years ago.
What I am doing and would suggest you to do is to go there and after finishing the assessment successfully ask them as many questions as you can accenting on the self-sponsored students employment.
