It's important to note that:
* Kumon levels don't directly map to specific grade levels. They assess individual skills, not age-based expectations.
* Individual student progress varies. A child might be at G150 in some areas and ahead or behind in others.
* Kumon focuses on mastery and building a strong foundation, so a student might be working at a higher Kumon level than their grade level in school.
If you have specific questions about a child's progress in Kumon G150, it's best to consult their Kumon instructor. They can provide personalized feedback and guidance.
