OP should of had a back up system. Something to fall back on.

imo if you arent saving projects on a usb youre doing something wrong.

ya I get side tracked by YouTube and craigslist

Duuuuude you shouldn't have gotten a Dell!

You should always back up important documents, pictures etc. I use a three prong back up for important documents. Flash drive, print out and I email myself a copy. Because there is always that chance your computer will crap out or get stolen and those things never happen at a good time (like there ever is a good time for that to happen).

@36 No, you can't expect computers to crash, but op said this was last period. In other words, he/she waited until the last possible moment to prepare. So, its still his/her fault.

I agree

This honestly sounds like a poor excuse for somebody who slumped off until last minute and then exaggerated a story of how it didn't get completed YDI

They usually give you a few days to prepare presentations. OP could have used library computers, a friends computer, or even an iPad. You can make presentations with those too. Plenty of ways to get around. So if I was a teacher, and if someone gave me an excuse along the lines of "My computer broke". I'd pan-fry them.

Lol. The principal isn't going to hold his hand and help him through it. This is a YDI

op pissed it off

No, you're just a student who has yet to discover the responsibilities of real life.

Teacher: "Your computer was smoking? You think I'm responsible for your computer's drug habits?"
