Best Answer - Chosen by the Asker Off the top of my head, "to finish" has a meaning closer to "end", whereas "to complete" has a meaning closer to "fulfil". Here's a quick comparison: "I finished my studies..." this tells me your studies simply ended. Perhaps you graduated, but it's just as possible that you gave up, quit or were kicked out of university. "I completed my studies..." this is very clear. It means that you passed your exams and graduated. If you're talking about work, use "completed" to mean you fulfilled all the required tasks.

It depends on the context your using... They are all pretty much meaning the same thing. Ive noticed and Usually Finish and End are used in past tense terms Ex: "I had to finish my test". We usually reserve finished and end for after the assignment. However complete can be used in almost any context. "I have some work i need to complete" which can be used properly before the task. None of them are incorrect though :)
