Hello Pablo! There are ways to find out what your level is. There are many free online tests for grammar/vocabulary level and also one conversation with a professional teacher is usually enough for them to tell you what your level is in Speaking.You may be at a different level in Speaking, Writing, Reading, Listening and Grammar. There are checklists that tell you what you need to know at which level - in the common European framework.
