Presentation class Level 4

Hello, my name is Francesca Espinoza. I studied history of art. i finished all my class ecxep level  4 of English. Then, to finish my career and i can graduate, i need to pass level 4. That's why now i am doing the level 4. My weakness about learning English are that i don't know a lot of words in English, my vocabulary is too poor, then sometimes i dont know what words i can use. My strengths are that i know someone grammatical structure, like the use the present and past simple, use the present and past continuos, use the present and past perfect.
