Grammarly.com/edu gave me this access code to share with as many as possible: 4zaHcT2qjL2HuD4D It gives teachers and students access to their online essay feedback (plagiarism and grammar). Seems decent; enjoy!
No problem; thought I should be adding to the great links on your feed : ). It is a 60-day free trial. Their goal is to, I'm sure, to hook us into a solid free service that we'll pay for once the trial is over. For my students, it is a free opportunity for their whole quarter. But yeah, good just 'til 3/30.
