I finished my GCSEs in 2015. During my 1st year of AS I fell ill, and then in my second year, I had an operation to rectify this. I am not 18 and I am starting my A levels at a local Sixthform college.
When I applied, the college informed me that they would receive funding for me, just not as much as a normal student. I had no issues getting back into the educational cycle.
Please note: I had not actually sat and A level examination at the time, I am unsure if the funding is just for your first set of A levels.
