Taking GAMSAT a year early

Hi guys, I am in my first year of undergraduate studies and hoping to apply for graduate entry medicine in September 2016. I know that I will have to take the GAMSAT and as far as I understand GAMSAT results are valid for 2 years. So would I be able to do the GAMSAT in September 2015 when I will be in my second year of Uni, even though I don't apply for medicine until September 2016. Has anyone done this before? Because in that way, I will have my GAMSAT results in my hand by the time I apply. Thank you for all your help!
