Silly question: was this summer considered eleventh or twelfth grade?

So I did an internship over this summer but idk wat to put for which grade I did it on the college application. The summer was between 11th and 12th grade but which grade was it officially?

For the Common App, it would be 12th grade.

I know you have the answer, but just an explanation. Once you have finished a grade, you are said to have graduated to the next grade. They could have a ceremony after finishing each grade, but they don’t. But you have completed the requirements for that grade once you have completed the exams or whatever the requirements were and they have certified that you are eligible to go on to the next level, usually within a week of the end of the term, more quickly for graduating seniors.

But when you think about it, after that ceremony in May or June, you are a high school graduate, so you wouldn’t say in July that you are in 12th grade.
