A doctorate in Spanish is difficult to read. I know a doctor who is studying Chinese-western translation here. It took him five years to read his thesis before he passed it. The tutor here is very serious about doctoral teaching and relatively careless about master's degree. After all, Spain has a master's degree, which was three years ago. They are very demanding of students and generally don't release water. You must reach the level required by your tutor. Don't push too hard. Because of the lack of classes, China students studying for doctoral degrees in our school just ponder over their papers every day. Get some translation work and earn some money.
