That is expected for general education - it mostly consist of knowledge that won‘t end up in professional or daily use. It still provides a rough scaffold of orientation and a potential later specialization. For example: I had to read and summarize Emil Zola’s Germinal. Never used that again (until right now 😃). Still - tacitly changed my view on life.

Research how much ATP your mitochondria produce daily to keep you alive and moving... Look at a YouTube video of a model of the rotating molecular motor that manufactures that chemical power for you. Consider that mitochondria are common to all living things.
To me, they evidence the mind-shattering genius of Jesus/God, the Designer and Creator of all things.😆
