My dilemma is where to place my son at this point in time - whether I should continue with Preparing or move him up to a higher guide. As far as his current abilities, he is very bright and is an excellent reader with fantastic comprehension skills. He has done extremely well on oral narrations, even from a young age, but has never done a written narration, other than book reports for English. (He is currently finishing up R&S English 5, at the rate of a lesson a day.) He can write several long paragraphs in cursive; however, if an assignment involves a lot of writing, he would prefer to do it orally. He is almost done with R&S Math 6 and finds it to be very easy, although it takes about an hour or more a day, between the lesson and assignment. He struggles in spelling and has taken longer to get through the dictation passages, due to small errors. (Because of his struggle with spelling, I've added in R&S spelling to the mix.)
He often needs more time to finish an assignment than would be expected, partly because he is a perfectionist and partly because he gets distracted. He is not the "check it off and move on" type of child, but rather is the "rabbit trail" type. I often have to redirect him or he would go on for an hour discussing something relating to the lesson at hand. I love this about him, but I also have to work within the hours we have available.

I own Preparing and all of the books, including the extensions, and I had really wanted to go through the guide with him. When we started Grandpa's Box and some of the other books, my son loved them and begged for more on a regular basis. Along with that, I like the idea of the gradual progression of skills in the guides and am concerned about him missing the skills taught in Preparing. The problem is my son is finishing 5th grade and will turn 12 in August, so if we pick Preparing back up now (and resume in the fall), he'll end up missing several guides at the end. I've pondered a few options to get us back on track. I've considered just doing Preparing as written, along with the extensions, and not worrying about missing any later guides; I've considered doing the guides 5 days a week for the remainder of my son's schooling, to try to catch up; I've considered trying to "rush" him through Preparing by doing two units a week; I've considered homeschooling all summer; and I've considered skipping Preparing and moving into CTC. I truly don't know which is the best option. I worry about making school drudgery by pushing my son too fast, yet I don't want him to miss any of HOD.
Any thoughts?
