Condensing Modules 3-6 into 3 yrs…..

Hello! Sorry I haven’t been around as much in a while. Lots of new possible school choices for my eldest requiring lots of research on my part.  But I still pop on here about every day:) Anyway, I’m thinking I want to have my youngest (5th) finish out the SCM cycle by 8th.  We’re currently using the Greece guide.  Any suggestions on how to squeeze 4 guides into 3 years? I’m not opposed to doing something different for Bible…maybe that’s my best option. What would you do:) Thanks for any input!!  Blessings, Gina
