Arts student's struggles with writing

[muhezixif]

My question may seem a little bit off-topic, but I didn't place it deliberately, so please, sorry. I'm in my first year in college and I prefer to spend all my time in ArtRage and it's obvious. Unfortunately, I have some other disciplines to study, and professors assign me too difficult writing tasks sometimes. I have an average talent for writing and no one for editing. If there is someone who shares the same peculiarity, please tell me how do you deal with these challenges? Are there any fast and easy solutions, or should I obtain proofreading skills by myself?
