I have 4 kiddos ages 14-5. I am really leaning towards using HOD with all of them for the upcoming school year. This will be our first time using HOD. I printed out the Placement Chart this afternoon and sat down this evening and figured out where my 3 oldest kids would fit. My oldest two (14 & 12) had circles all over the place...mainly when it came to grammar and writing. How do I know if they are able to use DITHOR if I've never used it or have seen it? So those blocks are hard to decipher where exactly they would fit. Neither has had any formal literature study aside from being given a stack of books to read and when they finish one, we sit and talk about it. That's been the extent of their literature study. My oldest can write in cursive, but my 12 year old son cannot. He's starting to learn, but has not mastered it yet. My biggest concern is, they both are strong readers and can comprehend and discuss what they are reading really well. It's just their handwriting and grammar skills that are lacking. So, I am just curious if I am able to purchase a guide based more off of where they score in the reading, history, and science columns, and then tailor the handwriting and grammar to fit where they are? I may even use an entirely different grammar than Rod and Staff, so this is also another thing I need to consider as well, I guess. I was looking at some of the books in the guide that my daughter placed due to her grammar/handwriting and alot of the books she has read already...a few years ago. So I feel like, comprehension wise, I would be holding her back just because her handwriting isn't up to par and her grammar skills are lacking a bit. Does this make sense? I would appreciate all the help/advice/guidance you all could provide.
My 8 year old daughter, who will be 9 by the time we officially start our new school year, placed where I thought she would in Bigger, however, she is definitely more advanced when it comes to reading/comprehension/and spelling. She's the opposite of my older two when it comes to the language arts. Those are her strong subjects, math is where she needs a little more time and practice. However, we have been using Masterbooks for her math this year and I am seeing such an improvement that I have no plans on changing that going forward. So, I am wondering if I should start her in preparing, not letting math hold her back, instead of Bigger. Or, no since she is just starting to learn cursive?
And then...on top of it all...there is the topic of credits for my oldest and how I figure all that out! Sheesh! I am starting to feel the stress of it all and I would truly appreciate, again, all the guidance you all can throw my way!
This is a lot harder than I thought it would be! LOL! Man how I wish I would have started with HOD from the beginning!
Thank you all so very much!!

EDIT TO ADD: I forgot to mention what grades/guides my oldest are. For my 14 year old DD, she will be going into 9th grade and placed in Resurrection to Reformation. My 11(almost 12) year old son will be going into 7th grade and placed in Preparing and RtR. (Preparing due to grammar and writing, RtR due to reading independently and age)
