She past the 1A with flying colors but needs some extra help with 1B (mostly because of mulitplication).
I looked on the placement guide at the site and it lists 1B and 2A as a typical 2nd grade year for the average student.
If we're going to use BLHFHG, how would this work? I need to just order a manual and start looking through it, with all these questions that I have.

My impression is that the typical BLHFHG student is going to use 1A/1B or 2A/2B.
So how would we incorporate the 1B/2A into next year?
