English Language Challenges

Hi everyone, in this few last week today I will write you about my experience with english language at university.
Well, for be honest all the things that I know about english I learned in school. I've had english courses since I was on third of primary school, so I have learned this language practically all my life.
Here at the university I enter in english III the last semester, but when I've told that I had to take an english course, the first thing that I thought it was that this english course it will be about technical stuff of the career, like the name of compounds, the instruments of the laboratory and things like that. So when I found that this courses it will like the regular english class, I have to admit that I was a little disappointed 'cause I was really excited about learning chemical thing in english...
The first course that I take here (english III) was a good experience because I could remember a lot of the things that I have forgotten, also the professor (Victor Rubio) was a really good teacher, he made dynamic class, the ambient was very nice and in occasions he give us little pieces of chocolate.
Here in english IV, I have learned a lot of how interact with people when I travel, of course I know how to establish a regular conversation, but the things that I've learned here more like how to interact in a hotel, if a I have problems,etc that will be very helpful when I have to go out side the country.
I things I need to improved will be the vocabulary 'cause some times I don't know the meaning of the words and practice more the reading part.
