Hi, my name is Cristóbal Mena, I'm 18 years old, I'm studying Chemistry and Pharmacy, I think my strengths at English are the structure of sentences, grammar skills, etc. because I attend other courses of English which taught me how to write in different tenses, but I think my problem was that I didn't study more words, I don't have a big vocabulary, and that entails that I don't have nice skills at talking, reading, etc. so I would like to improve my deck of words to this semester.
