I don’t remember if it was sixth grade or seventh grade, but either way it was before or slightly after my bar mitzvah. I know this because I was in Hebrew School at the time, and the year after my bar mitzvah—known as eighth grade by all the goyim—I left Hebrew Junior High School for something more interesting: Hebrew High School. These Jewish studies, which supplemented my mainstream public school education, were both irrelevant and relevant to me at the same time.
The irrelevancy is evident from this story, since Judaism and what I am currently writing (and what you are now currently reading—both the same) have nothing in common except for the initial location.
