Thanks for your advice everypne.i understand what everyone means. Yes i would love to get an a level in maths, not redo the whole sixth form. And yes it seems weird that i like maths and im aiming for medicine, but plans change all the time, im still in year 12, so people say i should do engineering, people say with medicine or dentistry i am garunteed a job because of its demands.. In the end its all going to come to what i love. I love physics/dt/maths/chemistry, but i also enjoy medical treatment etc etc. Its really hard to decide, all i NEED to do is put 100% effort for my summer exams, so after i get my results it will help me when choosing. Btw in unis for medicine/dentistry chemistry is always compulsory, yes biology would help, but in university they teach you biology all over again, its the key chemistrg skills thats important, biology is important but its mostly remembering a load of info. And plus i am going nursing home once a week every sundays for 3 hours, and ive been accepted into a hospital to work as long as 2 weeks in the summer or more, which i have already had my interview. So even though i dont have biology, i have good work experience, and if work hard for my exam, chances will be bettet, im not picky with unis you see, i juat care about getting the degree and enjoying my job not too stressed abouting ONLY going to cambridge..
