Education woes

Hi I have a 16 year old son with Aspergers syndrome. I am coming up against brick walls with his education. He has recently started sixth form and is getting no help or support due to finances. If he had gone to the local college he would be getting extra help and support.  Can anyone tell me if there is anything I do to help him or gain extra help because he is currently failing due to the changes he has made within this new school year. I am aat my wits ends and so worried that if nothing is done now his whole life will be affected.

please help!
