Thats really tough and I'm sorry to hear you have not yet had an interview. What degree classification do you have? Do you have your GCSE's etc.? Could you do more voluntary work in schools or even a museum to boost your application? I completely understand your frustration. I think many of us have been surprised by this round of PGCE applications across all subjects. Can you get any specific feedback from the ITT providers to say what they are looking for. I never realised getting on a training course was so difficult. I'm sure job interviews are less demanding! (Speaking as a governor who has interviewed quite a few prospective teachers). I hope you get onto a course very soon. Good luck.
