Love the dress HMC, my DD1 has the same one in navy for the year 13 leavers ball.
No year 11 prom here as it's a split high school county - years 7-9 at middle school then change school for year 10 and 11.
So they have a prom at the end of year 9, which is actually lovely because they're still sweet and innocent enough to wear proper girly prom dresses and there to be no thought of alcohol or after parties!
DD2 is having a party here on Saturday as an end of year 11/end of exams celebration.
She's invited most of the cohort - luckily we have a big garden and understanding neighbours . . 
Back to the GCSEs, Chemistry AQA got another "not too bad"
Resistant materials (aka woodwork!) tomorrow.
Not one she's really bothered about though (D&T compulsory at her school - don't get me started!)
So she's been cracking on with Physics this afternoon.
