No More Mistakes With This Grammar Cheat Sheet

The cold, hard truth is that the autocorrect feature on your phone and the spelling and grammar checks in your word processing software aren’t enough to guarantee error-free writing. And text speak never cuts it in academic and professional settings or in serious personal circumstances.

Even if your class or major is unrelated to English, strong writing skills are crucial in any endeavor or career. Use this grammar cheat sheet to check yourself, and make a note of any weak spots you have or things you tend to forget or mix up. Keep a physical or digital sticky note on your computer, and glance at it any time you sit down to write.
