There are some very good tutorials on the Bedford/St. Martins Exercise Central at http://bcs.bedfordstmartins.com/exercisecentral/tutorials.html . Look at the list of tutorials and choose the one that names the grammatical problem you want to learn how to fix. After you look at the tutorial, you can try the Exercises which all give you immediate feedback on whether you selected the correct answers. You will have to register for the site. Do not include your instructor's email address, since this is not required for a class.

To get better at writing, you should try to learn how to fix the common grammar, mechanics, and punctuation errors you have in your papers. It takes a lot of practice to break a bad habit, so don't get discouraged you keep having trouble with a particular type of error. Your goal is to have fewer errors as you get more practice recognizing and fixing your errors.
Here are some of the errors I might have identified in your papers. I have linked the errors to the website Guide to Grammar and Writing, which has explanations of the rule with practice quizzes which give you immediate feedback so you know if you are understanding the rule correctly. Also, some of the errors have Powerpoint explanations of the rules which are easier to understand than regular text explanations. You can also listen to podcasts and audiofiles from Grammar Girl.
