The MSci degree offers you the chance to also take research-based study in your fourth year. There are two types of MSci degree available via the Natural Sciences route: the MSci in Natural Sciences allows you to take modules from a range of subjects, but you would normally specialise in at least one of the following subjects in your fourth year: Chemistry, Computer Science, Earth Sciences, Mathematics and Physics. The MSci Joint Honours degrees are available in the following combinations: Biology and Chemistry, Biology and Physics, Chemistry and Mathematics, Chemistry and Physics, and Mathematics and Physics. The key characteristics of the Natural Sciences degree at Durham are choice, flexibility and depth. The Natural Sciences degree programme has a wide choice of subjects and there is also choice between modules within subjects. It is also a flexible degree programme and with most subjects you can delay choosing your subjects until you get to Durham and you can also change the shape of your degree at the end of the first year.
