What's up mates

so tomorrow I'm going for my first interview (EVER) as a computer teacher and I really need help nailing this job

I have a feeling that he's going to have doubts concerning my age (barely 21) but I know I can convince him about the youths being more closer to children and understand glow t poo hey learn....

Aside from that, there's still the issue of not knowing the type of questions I'll be asked

Please help a brother out
