On my site, I take students through two Lingua Latina books.

Here is the difference.

There is the main book, Lingua Latina.  It’s the one you are reading.  Familia Romana.  I have taken students through all of that book, and those classes are up on my site.  They are available 24/7.
Then there is a second book, Exercitia Latina.  As you know, at the end of each chapter of Familia Romana there are three homework exercises.  Pensum A, Pensum B, and Pensum C.  In Exercitia LatinaMr. Ørberg essentially adds twelve (on average) more Pensa to each chapter.
For the last year, I have been taking students through Exercitia Latina.  We made it through the first 19 chapters.  Those classes are still up on my site and are also available 24/7.
In August, we will resume with Exercitia Latina lesson 20 and we will hopefully make it to the end.  
After that, I may re-start Lingua Latina Familia Romana.  Or, we may just move on to Roma Aeterna.  Haven’t decided.
I record every class I teach, and I only take them down if I am updating them.   Currently, there are around 2,000 videos all arranged by units.  In other words, you could go from beginning Latin to advanced Latin easily on my site.  

I have quite a few students who use the previous classes only.  In fact, many prefer this as they can move at their own rate.  Students are always welcome to contact me if they have any questions.  

There are also forums for each class.  In the forums, students can interact with each other and ask questions.
