Undergraduate / My year as a foreign exchange student in the US, Common Application / own topic [4]

Hey I am a german Student who wants to apply for college in the US. I am not very good in writing essays. So please tell me what is wrong and how I could write my essay better. Thanks

My year as a foreign exchange student in the US was an amazing experience and changed my perception of school and the people in my sphere. I stayed the year with a very kind host family, which chose me from about one hundred exchange students applying for a year in the land of Stars and Stripes. The city I lived in was about a two hour car drive from New York City and approximately two hours from Boston. It was a great place to be in and everybody in the town was friendly. No one said bad things about me just because I am from Germany. The longest time I have ever been away from my parents was one week, but now I was four thousand miles away from them for a whole year. I had a difficult time the first couple of weeks, because I missed my brother a lot who has always been in my past for the last 16 years. Something what helped a lot was that they called me almost every day, but it was just not the same as being with them. I had a lot of friends and I was pretty good in school. The courses I took helped me finding out what field of study I want to take. I took a lot of Computer classes and learned so much about it that I think tanking computer classes in College too. I also got interested in engineering and architectural. I had a great time with my classes and I always had a luck taking the classes I like. My host family helped me wherever they could and wanted to let me see everything about Connecticut. So they drove me and my host brother to Hartford to see the city where a lot of insurance companies do have their headquarters. We also drove all the way to the beach in Long Island in the summer, so I can see the Atlantic Ocean. I also played hockey at the school hockey team. The Team was wonderful and very kind. They accepted me right away and helped me get into the rough rules of an American hockey league.

I changed more. But I know I still have to use more professional words :D thats just the rough thing I want to write in it.

Thanks for all the reply
