Do the Practice Questions match the video lessons?

The quiz categories do not match the chapters in the book or the video lessons. They are designed to (loosely) match the official EA test specs that are listed in Prometric's EA Exam Bulletin, found here:

The video lessons and the accompanying PDFs do match the order of the PassKey book chapters, however.  

Practice Test Categories (for Part 1):

1.1 Preliminary Work with Taxpayer Data  

1.2 Income and Assets  

1.3 Deductions and Credits  

1.4 Taxation and Advice  

1.5 Specialized Returns for Individuals  

As you will see, the categories match the categories in the official Prometric bulletin (link above). I hope this information is helpful to you. And good luck on your exams.
