The experience of taking driver license

What is the first thing you should do once you are in the United States? Passed driver license! You will need it as your passport. When you buy liquors or lotteries ,go to pubs, and shop by a credit card,you have to keep it with you all the time. I had bad experience about taking driver license in AZ. Three years ago, I was a new student in U.S. and my English was too poor to communicate with people. A female employee who was my drivering test invigilator asked me to park my car alone a white line. Unfortunately, I couldn't understand her direction because of her "high speed" speaking. I've asked her to repeat and slow down but she just ingored my asking. After 15 minutes,I still couldn't figure out what she wanted me to do then she became to lose her temp and got mad. I couldn't forget one thing she has talked to me that "Can you understand English? If you are not, why are you taking this test." I was very mad while I heard this question like discrimination. Of course,I didn't pass the test at this time. I asked her the reason why I couldn't pass it. Guess what, the reason was I drived too slow before the stop sign. Was it a reasonable reason to fail me? Who doesn't slow down before the stop sign? What can you do if you were me? Sigh...the only way was just taking the test again. You need a driver's license,don't you? Today I went to DMV(Department of Motor Vehicles) in CA and passed my driver license. I will get my new ID in two to six weeks. I only took writting test because I have had an old ID that was issued by AZ. The writting test has two parts of questions if you decide to take Chinese virison. First, you will answer 36 questions of road rules in CA. Second one is traffic sign part and you can see 12 signs on it. You can not make errors over 6/36 and 2/12. In addition,You will get an instruction permission after you passed the writting test if you don't have an ID of another states. In 14 days, you can practice to drive on the road by accompanying a person who has driver license and age over 18 years old. After that,you can make an appointment to take driving test within valid dates. As above, you can receive your ID within couple weeks. I have some materials of driver license that include Chinese virison questions and traffic sings. If you are interesting in this you can mail to me.
