Are they stopping EMA? If so when does it take place and why are they doing it?

I'm 14 and I'm currently studying my gcse's I am really interested in medicine so want to stay in school and I heard they are stopping ema, which will make it harder for me to get by as a student. My brother got paid to go 6th form so why can't I? Will I still get Ema when I go 6th in 2012/13. When will they stop giving ema to students and why are they doing it?
