It is not possible to grade your level of English writing based on such a short sample of your English. You have made quite a few grammatical errors but I have no idea whether your short sample is typical of your normal English writing. The only thing I can reasonably say is that your writing shows consistently incorrect usage of capitalisation (you haven't actually used any!) and the other errors are grammatical so working on different grammar structures would be of benefit to you. The errors are mostly minor and do not obscure your intended meaning, at least in the couple of sentences you have given here.
