Hi Mikado,
Welcome to the hobby!
In addition to the reference links provided by Hamtest, I recommend getting a copy of the ARRL Handbook. It's a reference that you will find useful not only as you study, but for years afterword (and I hope you will continue to learn about all of the aspects of the hobby as years go by!).
The ARRL Handbook for Radio Communications 2013 softcover:

The ARRL (American Radio Relay League), in case you don't know, is the national association for amateur radio, with approximately 170,000 members nationwide. I encourage all new hams to consider joining:

I believe the League to be a great resource and they are the only organization that represents hams as a group to help keep the hobby strong over the years.
I also recommend joining a local club, as soon as you get your license.
Hamtest is a great study tool, but it's only the beginning!
Good luck on your tests and let us know how you do.
Jim
