It sounds an easy task to choose your LLM subject. It is also a daunting task with the number of courses and providers overwhelming. Before choosing your subject area you need to consider Law school, location and your future career.
Here are some issues to consider when you are choosing your LLM.
Your subject interests
The LLM dissertation is a mammoth task so it is vital that you have an interest in your chosen subject area. Hopefully when studying your LLB you will have developed a preference for some areas of law over others. This will help you explore your preferred options and narrow them down to a short list. Your shortlist may also be determined by the career you intend to pursue. If you wish to lecture in International law or hope to join a firm which tackles corporate fraud then your chosen subject will be tailored to reflect those preferences.
If you are not influenced by your future career then you may be advised to choose a subject in which you excelled at undergraduate level. If you have a good understanding of a subject at LLB level it should be easier to study it at LLM level.
Online (Distance Learning) or LLM by Research
An important consideration is the manner in which you intend to study. Postgraduate study in law can be taught by online/distance learning or LLM by Research qualification.
Both the delivery and structure of each of these course types are different. If you are working part-time you may have to subscribe to distance learning. This type of learning allows flexibility but requires self discipline and independence. If you are not tied down you may be suited to module study, lectures and tutorials similar to those in your undergraduate degree. Many students like the idea of face to face tuition offered by the LLM by Research.
