哪个入学要求更高一点？哪个更难毕业？
參考答案:I respect Rele2, but I can't agree with him/her this time.
The name of the degree reflects the method of study and/or the goals of the program.
MPhil is Masters of Philosophy and PhD is Doctor of Philosophy. They are research based programs and all knowledge eventually lead to philosophy, which is the foundation of everything.
MPhil is to verify old or current knowledge, but PhD is to create new knowledge. Any candidate can register in an MPhil or a PhD program upon graduation from their Bachelor's. An MPhil graduate can move onto a PhD program, or a PhD candidate can opt to graduate with an MPhil if he or she fails to produce new knowledge. Every PhD has an MPhil component. The goals are different. The purposes are also different.
In a law school in USA and Canada, LLB is a graduate program to train lawyers who have an undergraduate degree in any discipline. LLM is a research degree, very similar to a PhD, though LLM is also an advanced degree in law skills. There is a JD (Doctor of Justice or Doctor of Jurisdiction), which is an academic research program in law, but graduates are not entitled to any qualification for legal practice.
If you have an LLB, you can register for either LLM or MPhil, but their focus is very different. For LLM, probably your goal is either to become a senior law practitioner or a professor in a law school. For MPhil or PhD or JD within a law school, your goal will be within the academic world.
