Keeping in mind HOD's recommendation to study English 3 during Preparing, I am frustrated!

I do think R&S English is a fine program with an excellent reputation. The lessons are short. It is very thorough. However, I think we are having a HUGE disconnect with it. My oldest is using Level 3 and it is too easy for him. While I agree that it is a fine thing to have a subject that is easy, it is not proving so for my kiddo. The easiness leads to boredom and "checking out". He doesn't have to engage his brain with this subject. R&S is incremental, giving new information in easy to digest, bite size pieces. But, this is proving to be tedious for my guy. I have been thumbing through Level Four and find the material to be more "on level" for him. I want SOMETHING to challenge him! My son doesn't seem to fit "just right" in a HOD guide right now. He is more than ready for Preparing but we have chosen to keep him in Bigger for some character growth

and to keep my schedule doable. He likes the work but is IS easy.... I think he's academically ahead of grade level due in part to his age (he started K as a nearly 6 year old). NO subject challenges him and English is no exception. I am torn between agreeing with HOD's recommendation and doing what seems better for my kiddo. I don't want to push unnecessarily but I do believe, firmly, that growth requires challenge. The challenge creates an opportunity for us to stretch, to fatigue our mental muscles, to build up endurance, to depend upon the Lord, etc.
Any thoughts or advice? I believe that R&S's format and pace will be fabulous for my 2nd son

. It's just my crazy, quirky, creative, dear, outside-the-box oldest child that seems to need a slightly different approach than "the usual".
