graduating class size \ Counselor's name

Hello
Im an international applicant planning to apply to a university this year and they asked me about the graduating class size and a counselor’s name in the common application.

i heard that the bigger your graduating class size is the better but in my country classes are all less the 45 student maybe i miss understand what they want so i wanna make sure if they want the size of my class only or the number of all graduated students with me?

about the counselor’s name do they mean a school counselor or what? cause i’m thinking of writing my sponsor’ name instead

Class size means the number of students in your school, in your grade, that are graduating in your year. Smaller or larger isn’t better or worse, it just is.

Counselor’s name is your school’s guidance counselor.

thank you soo mush
