Btec 90 credit diploma ucas point tariff help

Hi guys! So I'm studying Travel and Tourism and am currently into my second year. It is the 90 credit diploma. I am looking into unis at the moment, taking an interest in the Southampton Solent University and the Beauty Promotion course (I've decided Travel and Tourism really isn't for me). I'm just getting a bit confused with the UCAS point system. When I enter my results for last year into the UCAS calculator (i got D*D*) it says i will get 84points, I also took AS photography and got a B, being i have 16 points on top of that. However, is that 84 points for just last year and if i get D*D* again i will get another 84 points, or will that be for both the years if i achieve a D* this year too? Just a tad confused
