Hello! I have finally made it to the practice section of the study plan, but I have noticed when taking prep tests the questions are all from sections I did earlier in the week. Is this normal? And, how do I know my score is accurate and not just a reflection on how well I can memorize previous questions? I am worried I am not actually getting a true reflection of my abilities. Is there a way I can change this setting to get fresh questions for the prep test in my practice block section?
