Test preparation courses are for students looking to improve their performance on a test, usually for application to a higher learning program. Courses commonly focus on a specific test, providing insight into the style of questions as well as the information needed to answer them correctly.

Master-level studies involve specialized study in a field of research or an area of professional practice. Earning a master’s degree demonstrates a higher level of mastery of the subject.
Earning a master’s degree can take anywhere from a year to three or four years. Before you can graduate, you usually must write and defend a thesis, a long paper that is the culmination of your specialized research.
