If you read the first page when you log on to the course it tells you all that info about what the computer reconizes. I felt over whelmed with the lessons and quizes. Alot of my time was spent fixing all the spellings just so I got the good grade in the lessons. I just took the exam on 1-15 and passed and it was really alot easier than I thought it would be. Just learn the info and try not to worry about all the spellings of everything!
