That's definitely a sad experience and I know how much you have felt after missing the exam. I never had such an experience but there was an exam day I woke up pretty late and I was really scared.
I am glad you were able to take the exams later even though you have to rewrite the three subjects.
man waking up late and going late is something I've experienced...it used to be scary experience.
Like back then just a day before exam one of fear in mind used to be: what if I didn't wake up tomorrow - am going to fail.. that was a nightmare
But missing out completely was never on my card... Yet it happened unfortunately but it's past and turned into a good chapter of life.
Thanks tho!
