Biological Sciences is a broad subject allowing the completion of modules from a variety of areas. As you can pick your modules after the first year it also allows specialisation in certain areas at a time when perhaps you know more about what interests you than you did when applying for University at age 18.
During a Biological Sciences degree just some of the options of modules you can choose are Reproductive Biology, Ecology, Conservation and Cancer Biology, to name just a few. This diverse range opens many doors for future careers and as a degree gives you data analysis and interpretation skills valued by many employers.
