Each individual student is different. Everyone learns differently and at different speeds. We recommend a good benchmark of progress is making a goal of earning 80% on the Practice Test at the end of the study guide.
We also suggest you utilize the Diagnostic Test in the study guide as well. Since you only have 3 attempts at the Practice Test, you might want to take periodic Diagnostic Tests while studying. These will help you to see which areas you need to focus on more so you can better tailor your studying.
