Our school used to mail a copy of our report card to our parents (did that for IGCSE's).
They didn't do it for C1, so doubt they'll do it for A levels.
I'm sure the exam board wouldn't mail em, only hope is school.
You should be glad. Who would ever want to ruin an awesome holiday with a report card being constantly stuck at their face.
If you really want it bad, you can get a friend a relative to collect it (might need to provide a letter) and ask them to email it to you.
