I was disappointed by the scores on the review quiz.

The questions were the same or very similar to questions you have already seen. To do well on the review quizzes you should review previous quizzes and understand the correct answers. As I said in the previous post, it takes effort to learn something. If you don't make the effort, you are likely not to do well. If you make the effort you probably will do well. But it requires that you do the work.

That's right.
