<human>: So, after finding a flaw in our school network system where student accounts were able to access a 'teacher's shared area' relatively easily. I didn't explore any further however I stupidly decide to show off and tell (lets call him)'student-A' about what I had found and how to do it.

Turns out student-A then decided to do some more exploring, digging deeper in where student-A was then able to extract tests and coursework. To add to this student-A then started distributing these items to different people in different classes.

A girl then gets caught and questioned about how she has miraculously got the exact same answers word for word just like the mark scheme. She gives the name of student-A and he is taken in for questioning as well. (What may also have happened, is a search carried out on student-A where they may have found a USB containing these documents). Trying to find a way out of it student-A then blames me for showing him how to get into this shared area.

I'm pulled in questioned and asked to show how it is done in front of a member of the IT team. I'm asked who else knows about this and I am then sent of home with instructions to report back to school with my parents on Monday morning.

At this point they have no evidence I have taken anything from these files or distributed them. Reddit, is there anything I should say or do in my defence?

Give me a shortened version of the text
