The academic year starts on September 1 every year and ends on August 31 of the following year.
The educational work of every academic year is organized in two semesters, the fall semester and the spring semester, each of which comprises 13 weeks of teaching and two or three weeks of exams.

• Fall semester courses start in the last week of September and end in late January, followed by the first exam period of the fall semester.
• Spring semester courses start in mid February and end at the end of May, followed by the first exam period of the spring semester.

Every semester has two exam periods:

• Fall semester courses are examined during the exam period January-February and re-sit exams are held in September;
• Spring semester courses are examined during the exam period of June and re-sit exams are held in September.

 
The exam periods usually last for three weeks.
