When studying at college for the inital 2 years you gain a NC and HNC I'm just about to finish the NC within next 10 weeks or so hopefully and the HNC by christmas 2012. It is hard work so be prepared from the get go. One step at a time though and get through the aptitute tests. Can't really provide much information about it it's just general mental work to see if you could keep up with the work I'd say.
