Know you acronyms. Know your theory really well, if you know it well then there is no reason for you not to do well. Be calm. Resist the urge to write a note to the exaimner telling him how stupid he/she is and what a cruddy paper they set (due to the horrible scenarios they normally give )
Stupid things like:
"You are applying for a job with XYZ computer store, the manager wants you to fill in an application form. He wants to make sure you have sufficent knowledge to work in his store. Explain what the following terms mean:
1) Flaming
2)IRC
3)Blog
4)IM
5)RAM
6)CSMA/CD
etc etc
Paper continues in a similiar vein all the way through.
Often they give you an advert from a PC store with 3-4 different computers on. Then they ask things like: Bob is a gamer which pc would you recommend he gets?
You then have to answer like: I would rec he buy PC "C" because it has like 7364GB of RAM and 364GHZ processor and ATI 32824723 MegaDuper Graphics card.
Susy is a secretary, what do you reccomend?
Then obvioulsy same sorta thing but she is going to have the worst of the 4 pc's because she only needs email and word processing. (for example).
Then you get questions like: Sam walks into the store. He thinks that getting internet at home would be a good idea as we wants to give his children the best education possible.
Discuss the positive and negatives on having an internet connection at home... bla bla bla.
Sam heard that he needs a firewall and anti-virus. Explain what these are and if he needs it.
