Welcome to CNA Plus Flashcards! We now have another proven way to help you study for your CNA examination. Scientific research shows that using flashcards as a study method creates strong neural brain connections. This means your memory improves as you go through the flashcards again and again; this is called "active recall." You’ll also gain confidence as you realize that you know and understand the information. Flashcards are one of the most effective study tools, because you know instantly if you have the correct answer. Since you’re "grading your own work," you will learn more quickly and be able to focus on areas that need further study.
