<human>: Condense the text into a few key points

So, today was the day of an English A level exam. As I am an English student, this meant that two and a half hours of my morning were spent in a hall with about one hundred other people frantically writing. 

More importantly, a minor disagreement with my parents the day before meant that my mobile phone had been confiscated. As I wasn't very happy with this, I decided to take it back without their knowing, but hid it under the sole of my shoe to make sure they didn't find it if they were to check my pockets. It sounds odd, but this is something they've done in the past so I thought: "better safe than sorry".

Fast forward to the exam, i'm busy writing about drama and poetry I suddenly realise that I can hear my ringtone. For the curious, this is what could be heard: 

Thankfully, because my ringtone volume was low and it was muffled by my foot, very few people actually heard it. But there were definitely a couple people around me who were asked to 'test their might' halfway through their paper.
