"What level" refers to the year of admission; "Which session" refers to the year of graduation.

For example:

Xiaoming graduated from Fuzhou University, enrolled at 20 1 1, and graduated at 20 15.

It can be said:

Xiao Ming is in the class of 20 1 1 and 20 15.

Extended data

The difference between level and session:

1, with different definitions.

"Grade" means "grade" and can also be extended to "grade". 20 18 is accepted as "grade 20 18", also called "grade 20 18" or "grade 20 18".

One meaning of the word "conversation" is "restriction", and it can also be extended to "arrival" or "arrival". The word "then" means that time is up. The meaning of quantity is derived from "to", which is used for regular things and represents a complete process, which is roughly equivalent to "time" or "period".

For example, class 20 19 refers to 20 19 college graduates.

3. Different grades.

Senior one refers to the first year of school, which is the first year of college. For example, 20 17 college students refer to 20 17 freshmen.
