I have only been able to complete the very first study guide of "Explicit Meaning Novel and Short Story" but have not been able to move on to the practice question or at least the other unit. I understand that I do not have access to everything because we have the $149 plan, but why can't I at least move on to the study guides for the other units or do the the check for understanding questions? The only thing that is working is the create a practice test.
