“Our son loves the classes, and he is learning a great deal — not just about coding but about math, problem-solving, and hard work as well. We attended the school STEM fair last night. He ran a Raspberry Pi machine learning setup found from Google’s Teachable Machines website, adapting their Python code to his setup. All made possible by your class — We’re grateful!” — Montgomery County Public School parent feedback
