Level 1 - Primary.
This grade is the simplest and is designed for ages 4 - 6. It consists of a simple story with easy puzzles and colourings.
Level 2 - Junior.
Designed for ages 7 - 9, the Primary lesson has a more detailed story and more difficult puzzles. All the answers to the questions are found in the lesson text.
Level 3 - Intermediate.
The intermediate lesson is intended for ages 10 - 12. For these lessons, the student needs to use the Bible reference to find some of the answers.
Level 4 - Senior.
Aimed at teenagers, the senior grade requires the student to use the Bible a lot more to find answers to the questions.
