A lot of schools are open next week so try then,
I'm in the same position with maths but luckily I saw my maths teacher on the night I got my results and she was able to tell me my score and that I was being sent for re mark due to being one mark off the next boundary!
Generally if you're really close your teacher will contact you or a re mark will be done ASAP (with your consent)
Give them a ring Tuesday, if you get no reply go back on the first day of term, or the teacher training day if there is one.
