Nervous

I have learned Japanese in a language school,after graduated from high school.When the end of term,the system has a speaking exam which concerns you talk with a Japanese teacher by yourself in a big classroom,it looks like a EL TS speaking exam.I got involved in this exam.I have never forgotten those experiences since I took part in this talking.
It all started one hot day.Classmates and I were sitting in the classroom and waiting for the line.Some people was so nervous that went to toilet again and again.But some people have a normal heart in this exam.I was keyed up,my leg moved non-stop and heart struck quickly,Because I talked with a Japanese teacher at fist time,you must listen to sentences carefully and can not ask for help to other friends.My friends chatting joking with me,they distracted my attention to interesting things.That was my first nervous and the adrenalin was going in this day.
The exam was beginning in my nervous heart.After said hello each other,She asked me a little easy question.I was so nervous that I can not understand what she said.I got upset and watched with confused eyes.The teacher repeat the question again.But I can not understand too.Adrenalin was climbing again and my face blushed in this day.Because I only had two opportunities in the same question.The teacher told me do not worry about this talking and tried to relax.Though I finished this exam,I did not have a good market.
These were my twice nervous things in 19-year-old.I always tell myself do not afraid of speaking exam,but I can not control my adrenalin.I am not good at speaking exam.I always fear this exam,so my adrenalin helps going.To overcome my fear,I must talk much with teacher in her free time.
