L.A.
I am sorry your parents have this early curfew. I wish parents would be realistic about what it is like to be able to trust the good kids.
I feel like as a Senior in High School you deserve a later friday/saturday curfew.
My reasoning is that our daughter has always been an excellent student and very responsible.
Once she reached High School in general, there are just so many activities, school sponsored, that go later than 9:30, even on school nights. They had football games go into triple over time and not be over till almost midnight. That meant the players, Cheerleaders, drill team, and band members all stayed there till it was over.
Then they won the game, s every one went to the local hang out to celebrate.
I recall as they studied for their AP exams, they were out at Starbucks studying till 1:00 and 2:00 am.. Yes, they all passed!
Also since you will be attending college in the fall, this is a good time for you to learn about being out later at night. Our daughter would tell us what time she would be home. If she was running late, she would call. , But she also knew we did not sleep well till she got home, so this was not very often,
.. Our daughter studied at college all night long many times, and not in her room or her House (dorm).. They study in groups. They take breaks and go out for coffee or snacks.. It is all part of the experience. But because our daughter knew her limits from her experiences in High School, she knew to call it quits. To get enough sleep, to budget her time.
IF you speak calmly with your parents, maybe only ask for special events, Prom, Etc.. They will be willing to give it a try.
There is a rule of thumb, "Usually nothing good happens after midnight." But when a child is a good kid, of course there are exceptions. Act mature, responsible and grateful , and they are more likely to treat you that way.
