Since I jumped on the Grammarly board my writing has improved tremendously and my confidence has grown as well. In fact, I prefer Grammarly to Spell Check in my word documents. The only thing which keeps me wondering is the premium numbers giving an idea of the words I missed. If you are looking for something to help you or your children in high school Grammarly is a great choice. I recommended the app to anyone looking to improve their writing skills.
