There were a couple of concerns raised in this thread about several areas in RTR that I would like to take some time to personally address. I am always grateful for the opportunity to share my thoughts with those who are using the guides!
I agree that the history readings in RTR are a step up from the readings in CTC, which means that they are somewhat longer and more involved. However, we are assuming that the child is reading his/her own history readings at this point, which keeps the history readings to about 20 min. a day.

We are not intending for the parent to read the history pages aloud at the RTR level as this will definitely draw out the history readings making them much more time consuming than we planned for both parent and child. So, this is an area that can definitely add time to the day depending on who is doing the reading.

It is also important that the child be able to handle the level of reading in RTR in order to prepare him/her well for the readings coming in the next guide. There can be definite exceptions to our intended design of the plans, as in the case of children who have dyslexia, eye challenges, or a host of other issues that can play a role in a child's education.
As far as science goes, RTR focuses on earth science. There was a concern raised in this thread that the science in RTR is "very light". From our perspective, the science meets the science standards for the target age group of ages 10-12 and covers needed topics for earth science. It includes the entire Apologia Astronomy book as just one part of the science, when typically the Apologia book is meant to last up to a school year on its own. This alone should remove it from the "very light" category. RTR's science also includes living biographies along with all of A Child's Geography (which is physical geography that covers earth science topics). Last, but not least it includes a choice of Tiner's Exploring Planet Earth or God's Design for Weather and Water. There are 35 experiments performed throughout the year with lab sheets written with the scientific process in mind. From my classroom days, 35 experiments of any kind performed by the child with lab sheets far exceeds the number of experiments performed in many science classes. RTR's science also includes oral narrations, notebooking, and guided questions. From being in the public school classroom at a very privileged school teaching at this age level for years, I can definitely say that the science is enough in this guide.
I think that often families have a bent more toward either history or science. For those families who have a passion for science, there will always be the desire for more science as their focus. Or, for those families who desire a lab type setting with those type of experiments, there will always be a feeling that experiments done with household supplies are not really scientific enough. However, I want to encourage you that many of the greatest scientists started in home laboratories and some of the simplest experiments were the most life-changing.

Galileo's experiment dropping two different weighted items at the same time to see when they hit the ground and Archimedes' Eureka moment with the bathtub come to mind.
So, for those who desire a more textbook oriented or laboratory focused science, you can easily go that route if desired. But it's good to consider that just because you may desire a different approach to science other than what is offered in the RTR guide, it doesn't mean that the approach we use is "very light". It is just approaching the subject in a different, more living and accessible way.
Another concern mentioned in this thread was that the art appreciation book Looking at Picture is "boring". From my perspective, we found the book to be interesting, entertaining, and beautiful. My oldest sons and I deeply enjoyed our time spent with Looking at Pictures. Part of the difference in opinions may stem from differing goals for art appreciation. My goal in selecting this book was to schedule time each week to use this book in a Charlotte Mason style picture study fashion. I was not seeking to include an in-depth art study.
CM style picture study is something our family has pursued now for 10 years.

I must admit I was extremely skeptical about the simplicity of the CM approach to picture study in the beginning, but I have become a firm believer in it as the years have passed and my kiddos and I have learned to appreciate and love beautiful art. To that end, Looking at Pictures with its 150 stunning illustrations in full color from The National Gallery in London (including entries from Leonardo, Rembrandt, Matisse, Seurat, Picasso, and many more) fit the goals I had in mind for art appreciation.

We spent time studying the pictures, absorbing their details, discussing what we noticed, and learning to appreciate art in the process. Art study doesn't have to be long or in-depth to resonate. It just needs to be meditated upon and shared.

This is what RTR seeks to do in this area.
Last, a concern about the pricing of the Student Notebooks was mentioned. I'll just close in sharing that we have worked hard to make sure the full-color, custom-made notebooks are worth every penny that we charge for them. Full-color notebooks on specialty paper are not cheap to print, but even more than that the amount of time and money needed to create a notebook of this quality working alongside a professional graphic designer is staggering. When you consider that the Student Notebooks are typically one of the few parts of the HOD programs that are consumable, it makes it easy to see that we work hard to be sure that your money goes toward real, living books that can be reread and used time and again. The notebooks are meant to be a beautiful keepsake or portfolio of your child's school year. In comparing them to any other type of "scrapbooking" or "notebooking" out there, we are pleased with our notebooks quality, beauty, and purpose.

We pray that most of our customers will feel the same.
For each of your that are using RTR this year, we pray that the Lord may richly bless your time spent with this guide. It is our heart's desire that it would draw your children closer to Him and that it will ease the burden of planning your homeschool days.
Blessings,
Carrie
