Student in 2021

Hello! I was a high school student (a senior) in 2021. As I understand, to be considered a full-time student you would’ve needed to be in school for at least five months. I was going to school everyday, 5 days a week starting on January 1st and ending in the middle of June. I did not go to college after I graduated high school. The question I have a hard time answering is “Were you a full-time student in 2021?” I know it’s silly that I’m wondering this but I just want to make sure I’m filling this out correctly, and with me not continuing education past high school, I’m just wondering if me being in high school counts as being a full-time student. Thank you so much!
