Someone has stated that they have a 'Master's by research'. Does this mean that their entire degree was awarded based on their thesis work? Or does it mean that they took requisite courses, but also wrote a thesis?
In most institutes Masters by Research means they had to take the core courses usual Master students are offered but they also produce a compulsory Masters thesis in order to earn their degree. However, I have that seen in most cases that they have to take lesser number of electives so that they have more time for research.
