you wanna clear 15AU by the end of 2nd year. I dun think u can do it. Year 4 will have the highest priority standing and Year 1 with the lowest. Unless you wanna clear those unpopular module and quite unlikely you can get 2 PE/UE or one of each in 1 semester. Unless you are willing to spend 500 taking special sem then of coz. U can clear 15AU by the end of year 2
