Not so good

For a program that is supposed to teach and test english, it has misspelled words and incorrect words. Im sure these misspelled words were not intended. Even one of the test questions: all four answers were wrong, because the "correct" answer was a word that sounded like what the actual correct answer should have been.

Seems like this was created by somebody who is not a native english language speaker.
