YALL WILL I GET IN TROUBLE FOR THIS?!

Okay so my school isnt allowing us to go home for study leave until quite literally the final week. Today I had the most useless and ineffective timetable ever and was expected to revise in all the noise of my stupid classmates messing around. So, at break I noticed the gate was open and did a runner😭😭😭💔 Then I went home and revised for my history exam for 2 hours straight. Was so effective.

Will I get any trouble from this? Detention is not an option because those arent given to Year 11s.
