Hi Elena She is a seventh grade intramural student in the 2019-2020 academic year.

student of the seventh grade => seventh grade student 2019-2020 academic year => the 2019-2020 academic year intramural => ??? [boarding student if living at the school] She is a seventh grade student in the 2019-2020 academic year. or Currently, she is a seventh grade student.

In the US, we would never say that a student is “intramural”. We would say that of an activity (usually at college) My daughter’s at college and she plays intramural basketball three times a week. (She’s on a team with other students and plays in a league with other students at her college)

The sentence seems correct, except that I don't understand what 'intramural' means. To me, 'intramural' means between murals, between walls. OK, my dictionary explains it: Intramural is within the walls of a building or school, or city. It uses the example of 'intramural football' being played within the school (teams from the same school?). You could say the same thing with other words, e.g. a student from that same school?

Well, I meant a student who attends the classes personally. Maybe full-time then...
