How to Become a Tech geek in 72 hrs? Please do help!!!!!

Eeek....

So I am taking a cram course this weekend....anyone that can help...please do.

My cram course is going to be what people tell me or teach me or can direct me too.

I have to become something I fought my whole life ....over this weekend!

Literally when someone mentions technical garble my brain would turn off, I mean, I always had someone to help me....my dad, a boy....now I have an opportunity to show how quick I learn how to tell someone to map a drive, or the purpose of a IP or why you would Ping a computer.

Ugh......

Pointers or websites.....anyone????
