The London School of Economics has a fantastic reputation in both the United Kingdom and abroad. This reputation is justly earned due to the high quality of the professors, the renowned guest lecturers, and the high-profile status of many of the school's alumni. As is obvious from the University's name, the main focus of study rests in the areas of economics and political science. In other words, students enrolled at LSE are not receiving a liberal arts education, but rather an education that's largely designed to reflect the modern, international world at the present time. Students choose their department or major during their first year at school and usually take the vast majority of the classes within that department.
The professors at LSE are world-class. It is a common joke on campus that every Nobel Prize-winning economist has taught at the LSE at some point. In many cases, on the first day of lecture, students are shocked to find that their lecturer has in fact written the textbook on which the class is based. Due to the high-profile nature of the lecturers and the typically high enrollment in classes, students have to really make an effort to develop a relationship with the professor (they will certainly not reach out to you). On the other hand, the smaller seminars that go along with any class at LSE are usually taught by hard-working Ph.D. students. These students, trying to earn their stripes within the department, are typically very accessible and intent on helping students manage the massive amount of weekly reading that coincides with every class. To summarize, the lecturers are there to present students with the information, and the class teachers are there to make sure students understand the information.
