Not sure how to CITE sources? Working with MLA or APA (any class?)
ASK THE OWL! (Online Writing Lab...get it?)
This is where your professors will go to check formatting, citations, works cited pages, etc. so why not keep this in your toolkit for every paper?
There will be aspects that you start to memorize and just do without thinking (page formatting, in-text citations, etc.) but other things...like how to cite an conversation that happened on a blog two weeks ago...who can possibly remember how to cite that?
You may seem SMART to memorize every MLA rule...but I'd rather you be WISE enough to know how to look it up when you need it. Save your brain-space to tackle world peace.
Be WISE...like an OWL.
