Does someone here know how many years at the maximum one can take to finish MSc degree in Mathematics in Germany ? My friend enrolled for three semesters on regular basis but due to his mental instability he couldn't do anything. He almost has all the credits required and just needs thesis to be done. He is planning to take take a year gap to recover and may be finish his degree .
Is it possible for him ? Are there any provisions that restrict a person to take only certain number of semesters or that a person cannot take a year break or something of that sort ?
