I want to practice

I've been taking English classes for 10 months. My teachers are really good. At first I was a person that didn't know anything, but now I've been learning more and more each day. I want to improve my vocabulary and fluency, but I don't have any friends who to talk to.
I'm going to study medicine at university, so I have to practice my English.

If there are any mistakes, can you please correct them?

Things to improve:

- Ending sentences correctly: Whenever you finish an idea, put a period ( . ) and then capitalize (B instead of b) the next word.

- Always capitalize (use a big letter) the word "I" 

- Always capitalize "to"

I want to practice

I've been taking english classes for 10 months. The teachers are really good. When I began, I was a person that didn't know anything, but now i've been learning more and more each day. I want to improve my vocabulary and fluency, but i don't have any friends to talk to in English.  
I'm going to study medicine at university (in american English we say "at college", while the British say "university"), so i have to practice my english.

If what I have said is incorrect, you can help me to correct my short sentences. 

Great work Adrían! Keep up the good work!
