Always trying to fix things

I’m always trying to improve my writing. Yet, I find myself always stumbling around the same mechanical and grammatical errors. I don’t know what to do. Frankly, I suck at proofing and editing my own work, and that doesn’t bode well come term paper time. I usually get C’s and B’s on my papers because I cannot get the hang of things. 

Here’s where I get lost: 

  • Comma overuse: how to combat using the comma, too much.
  • Semicolons: is there an easily way to remember when to use this punctuation? 
  • Comma Splicethese things kill my papers, how does one get rid of them? 


There is hope for me, right?! Any assistance/suggestions/thoughts/encouragement would be greatly appreciated.
