My biggest problem is that I have hard time with more than one part when I'm writing an essay. First of all, background information about some topics make me struggle in the introduction. After struggling with the first part, come the body paragraphs, where I have to find topic sentences and supporting details. This part is still hard for me as well as the first one, because of my  lack of vocabulary specially academic words. Sometimes, I have great ideas but I can't write them down the way I want to. I realize that I have to read more often and practice a little bit more so that I can improve my writing skills.
