I am currently taking four subjects, one of them is further maths which I find it getting more difficult for me and I was thinking of whether to drop it or not. However, as I'm doing dentistry which I know is a highly competitive subject, I'm not sure whether dropping further maths, doing three subjects instead of four would make me in a less advantageous position. May I know is further maths actually useful for dentistry ? Will dental school take maths and further maths as separate subjects as if they don't than further maths would not be as useful I guess. Will taking three subjects instead of four make me less competitive in applying to dental school ?
