Mr. Duffy got rid of his layered curriculum. So. Don't judge. He's an amazing teacher. He helps you. But he gives long lectures. But you learn from them. Very leanent person. Always helps you when you ask.

Mr. Duffy is a great person, a really nice guy. But he literally doesn't teach. He does this thing called layered curriculum that forces you to relearn how to learn. Sound confusing? Well it was. He was quite literally the worst teacher I've ever had

Earth Science with Mr. Duffy was extremely challenging this year. I talked to several people, and they all agreed along with the students in our class this year that the workload of Layered Curriculum was over the top, not very practical, well thought out, or effective. Many of us failed, or just scraped by. I usually spent my time several hours in the day after school doing so much work, and not learning. Mr. Duffy is a good man, and very smart, but he should rethink the way he teaches.
