What I am Bad in English.(Time management)

In English, just about everything makes me dread doing it. Like a simple grammar exercise. I can drag it for 2 days. In summary, I am always in a rush to finish it so in the end, I end up with a crappy piece of work. In comprehension, I can finish it in time if i have thought up of a draft or planning.That is about it for everything on time management.

Things that I do not know or understand in English.

All this while from primary 1 to secondary 1, my English have been always my weakest subject although I do not know why.I do not take effort to remember any of the rules all their names.(e.g adjectives and nouns)I just read it in my mind and if it just sound good, I just put it in. So it is a half guess and half sense. In summary, my paraphrasing skill are quite average, only thing I am bad at are finding the points. In the question part, I am still okay with it although I do not take any effort to remember the types of questions. Thats all if you ask for comprehension though.
