I had the same chemistry teacher that my sister had four years before. She’d kept her entire chemistry notebook and presented it to me with the wise words: “You are going to hate this class. Use this.” The teacher literally used the same lesson plans, quizzes, and tests. And she let us write notes on one side of an index card like a limited version of open book tests. I would write the answers my sister got correct on the same tests on my index cards in the tiniest handwriting possible. I did end up hating that class. We NEVER did any labs because our teacher couldn’t be bothered to stand up or walk around at all. I learned more about chemistry from my eighth grade science teacher.
