I don't know what uni course :( Watch
I don't start applying until September, but still I'm freaking our a lot

If you do, you need to look for a Psychology course with Forensic Psych. units within it. Or a combine Psych and Criminology degree. Or you could do a more general Psychology degree and then specialise at post-grad level. Make sure any course you do is accredited by the BPS - http://www.bps.org.uk/bpslegacy/ac
If you do a specialised 'Forensic Psychology' degree straight from school you are restricting your future options. If you start with a more general Psych you will be FAR more employable.
