Overall, part-time education was preferred by most of students, while the other type was the big loser. Also, educational facilities attracted more and more people in almost every observed category with the only exception among men who studied part-time.
The number of male students increased in between full-time studies, doubled from nearly 100 thousand to 200 thousand by 1991. However, part-time education followed the reverse trend and decreased, but was never less than 850 000.

A significant increase in part-time postgraduates happened in 1990 and 1991, changing from under 800 to nearly 1200, though for the full-time curriculum a leap was made in 1980s.
