For each course students may find that there are additional costs. These may be with regard to the specific clothing, materials or equipment required, depending on their subject area. Some courses provide opportunities for students to undertake field work or field trips. Where these are compulsory, the cost for the travel, accommodation and meals may be covered by the University and so is included in the fee. Where these are optional students will normally (unless stated otherwise) be required to pay their own transportation, accommodation and meal costs. With regards to text books, the University provides students who enrol with a comprehensive reading list and our extensive library holds either material or virtual versions of the core texts that students are required to read. However, students may prefer to purchase some of these for themselves and will therefore be responsible for this cost. For students who wish to participate in The Lincoln Company's Edinburgh Festival Fringe performances there are additional costs. An approximate break down of these costs includes £570 for travel, accommodation and a levy to participate, and an additional £200-£400 to cover the cost of meals and entertainment during the trip. These costs are based on those incurred by individual students during the 2015 performances.
