At present, primary schools, junior high schools, high schools and universities are basically (1? ) session (? ) class

Format (20 1? ) level (session) (? ) class!

For example, 15 grade one 1 class number. 135 (135 means that your child is a first-year student of 135 who enrolled on 20 15 and recorded in the file), and there is also Class 25 (representing your child in Class 25).

Grade 20 15 (or 20 15) Grade 1 1 class, student number 25.

That's basically what it means! Mainly to facilitate the Internet (Education Bureau) to bring up children's files! It can be understood as your child's student status!
