The typical module has 3 assessments paced over the year. You are given at least 6 weeks to prepare your work on your computer and then upload it online by the deadline. The entry-level modules have two question sheets containing a mixture of maths-based problems and discursive questions. The third assessment may be an experimental report based on data supplied by the university, or a researched essay. Higher-level modules tend to have more challenging assessments that may be more open-ended or involve collaborating with other students. The BSc culminates in the Dissertation module where students explore an astronomy topic in depth under the individual supervision of a member of staff.
