I'm currently in year 12 studying biology chemistry history and RS, I did well in my GCSEs by getting 6 A stars and As but now at AS level I'm usually getting a D grade in bio and chem. Obviously I wasn't expecting amazing grades from the beginning but comparing my grades to some of the smarter ppl in my class, I think I'm on the lower end of things. I did manage a B in one of my biology tests with a very small amount of revision and I do really well in my chemistry homework so maybe I should just be a bit more confident? I'm doing okay at history and quite good at RS but I've looked at courses I can do with them and I'm not rlly interested. My target grades are also both Bs in bio and chem. I'm just worrying now bc I know I need to decide on something to do with my life and also need to get work experience sorted if I do choose medicine in the end. I think I am capable of getting As but A-levels are a lot more about effort, so I am planning on getting on the revision grind soon. Do I just revise loads and be more optimistic about medicine/dentistry or think of something else? My (doctor and dentist) parents and friends all say I should go for it and that I can do it. Any advice is appreciated!
