The reason I'm asking is because this past year, DD did not finish PHFHG (4th grade). I have really struggled with the decision of finishing it then moving into CTC or just start 5th grade with CTC. After months of praying and talking to my husband, the answer just popped into my head while I was in the shower this morning!
DD(10) will finish PHFHG using the left side of the plans (and science) and CTC's right side of the plans. I am so excited about this plan, but am wondering about the Bible study. Does CTC work better with the Bible study tied into it's history or should I just finish with PHFHG's Bible Study? I'm hoping this isn't clear as mud, and I know it's not a life/death decision, but I am trying really hard to plan ahead as much as possible and make sure DD stays 'on track.'
TIA,
JoAnna
We just finished CTC, and I do have to say that the Genesis study and the Geography study did match the historical time period oh so well. I'd be sad for you to miss all those great connections. 
Many moms do the left side of one guide and the right side of another, and enjoy that. But, I think it would be hard to start the right side of the guide when you are so far into the left side of another guide, and that it might end up undoing the balance of the guide and causing kind of an "off" feeling from here on out. I was thinking from a previous post that you only had 6-7 units of PHFHG left, but please correct me if I'm off here. As far as PHFHG goes, are you on the same unit and day of the plans for both the right and the left side? Or are you finished with some things and not others? Since you only have a month and a half or so left of it, if we knew that, maybe we could brainstorm a speedier finish so you could just start both sides of CTC at the same time?
