Theory test is too difficult

    I am worried so much about my Theory test that I have to take in 2 weeks time. The questions included in the tests are so difficult and I get nervous easily. And when you get nervous you forget everything you have already learnt. I am a busy person and I work 9-6 Monday to Friday so I should study for at least 2 hours after work which almost impossible for me because I usually fall asleep immediately when I come back home. I have all the DVD materials and books; I was reading highway codes etc. Still, I cannot stop panicking. But my best friend is telling me that I shouldnt worry so much because most of the things in theory test in just common sense. She told me I should not revise what I already know, I should rather concentrate on these aspects which are still new to me. She told me to stay calm and read the questions carefully several times before answering that way I will not make any silly mistakes as its easy to rush and think you know the answer especially if youve revised a lot. Of course, this wouldnt be the end of the world if I failed, but I would like to pass it during my first attempt and I hope it will be the case. I have a plan to buy a car soon and I already know what car it will be. But first I just have to pass my driving examination.
