I need you help with this ;)

Hi! I have an interview in a few hours and this is my presentation. I would appreciate it,  if you could correct this. Thanks! 

Hello, my name is Ana Lucia Diaz. I am twenty-four years old. In December, I received my Bachelor’s degree in Business Administration. I have lived in .....  [ supply the name of a town] for  seven years because I came here to study. 
 I was born in the capital of La Rioja, Logroño, which is a very hot and beautiful city, but which is smaller than CBA.[I don't understand this. You need to add the name of another Spanish city e.g Madrid etc.] 
I am now looking for work and I also want to improve my English. 
 In my free time, I watch TV series and play sports. I’m a hockey player at the  Universidad Nacional de Cordoba. My team and I represented the university in the local championship. 
I have been studying English since  I was 4 years old because my school in La Rioja had an agreement with ICANA. However,  at High School my parents decided I should change schools and they sent me to another school where the level of English was, unfortunately,  not so good. I therefore decided go to a private institute to retain and to improve my knowldege of English. 
When I began university, I stopped studying English, but now I want to improve my English for two reasons, one of which being that in July, I will be going to do a course related to my studies in an EU country and, of course, I will have the chance to visit many as many places as I possibly can. 
The second reason I want to improve my English is because I consider it to be very important for my future and I think that it will be of great benefit to me in both my professional and private life.

I hope the presentation goes very well. I corrected the obvuious mistakes and suggested more natural ways of expressing your ideas. In one or two places you will have tos upply some information: the names of cities or towns.
