How Do I Improve My Typing Speed In A Week?

I say practice everyday.

Definitely spend plenty of time typing.  The more the better.  To help increase your speed, try practicing typing in a time sensitive context.  For example, type numbers "one, two, three" and see how far you can count up to in a minute or so.  Keep trying to get faster.  Practice commonly typed words as well like "the, and, but, for, you, me, I, to, in, how, can, etc....".

It is important to practice typing real words, but also some typing games can help.  There are several free games online at www.freetypinggame.net that you can use to increase your speed. You can find other typing tools online there as well.  Good luck!
