Do I have to qualities to become a nutritionist/dietitian?

I am currently in my final year of high school and have been unsure about what career I wish to persue. I hope to go to university next year and do a course which I will enjoy. I am currently studying Maths, English, Psychology, Studies of Societies and Hospitality. I have come across the career of a nutritionist/dietitian, however it sounds like this course is heavily science based in the first two years. The duration of the course will be four years in total. I will be the first to admit that I am not overally strong in science, however I have great study habits and a strong determination to succeed in whatever I set out to do. Do you believe I would be foolish to enter this career path given the above details? Any help would be much appreciated, thank you!
