Well,time to study!
Here you can read and download (one by one) the audio of the 100 questions with answers for the Civic test in mp3 format. In the test they will ask 10 of the 100 questions, and as long as you get 6 right you are done. It does not seem hard.
Here you can find study material for the English test as well as for the Civic test.
Keep in mind that "You have two opportunities to take the English and civics tests per
application. If you fail any portion of the test during your first
interview, you will be retested on the portion of the test that you
failed between 60 and 90 days from the date of your initial interview."
PS: As you go for your Biometrics apt, you will receive a booklet and a CD with all the questions and answers, you may or may not want to wait until then to study
Are you ready to send all the documents? If you want to add a cover letter you can check this post. Also, if you want USCIS to inform you of when your application has been accepted, you can fill the G-1145 form which can be also found here. Once your application is accepted, they will inform you within 24 hours via email.
Well, now we got it all, so where do we send it?
I recommend to read the more detailed information here (then click "Where to File"), from were I pulled the following information. Roughly, here is the list of where to send the paperwork:
"If you live in Alaska, Arizona, California, Colorado, Micronesia, Guam, Hawaii, Idaho, Kansas, Mariana Islands, Montana, North Dakota, Nebraska, Nevada, Oregon, Utah, Washington, Wyoming, send your application for U.S. Postal Service to:
USCIS
P.O. Box 21251
Phoenix, AZ 85036
If you live in Alabama, Arkansas, Connecticut, District. Of Columbia, Delaware, Florida, Georgia, Kentucky, Luisiana, Maine, Massachusetts, Maryland, Mississippi, North Carolina, New Hampshire, New Jersey, New Mexico, New York,
Oklahoma, Puerto Rico, Rhode Island, South Carolina, South Dakota, Tennessee, Texas, Virginia, Virgin Islands, Vermont, West Virginia, send your application for U.S. Postal Service to:
USCIS
P.O. Box 660060
Dallas, TX 75266"
Now it is time to put everything in an envelope, write the address, send it and wait to be informed that the application has been accepted (as long as you sent the G-1145 form), and wait for the biometrics appointment.
Personally, I sent it through U.S. Postal Service with tracking to know that it reaches its destination safely. The cost was $5 and some change, and with the code you can follow the letter's path here. Sending it on a Saturday I know it arrived to destiny on Monday, and on Tuesday it was picked up. I received notice via text message that my case was received 10 days after sending it.
While you wait you can start or continue to study for the English or Civic tests. For more information about the tests and where to find study material read this post.
