Suggestions for Effective Quran Memorization Classes

Assalamu Alaikum, I’m looking for recommendations and advice regarding Quran memorization classes. I’ve been researching various programs, but I’m unsure about the best approaches to ensure long-term retention and understanding.

• What are the key features to look for in a Quran memorization class?
• Are there specific online or in-person programs you would recommend?
• How do these classes cater to different age groups and learning paces?

Additionally, if anyone has experience with Faith Consulting's Quran memorization resources, I’d love to hear your thoughts. JazakAllahu Khair for your input!
