The impression I got is they did not really try to teach you. That made me not want to work as much which made me do worse. I was interested in cars and wanted to work with engines and transmissions. I do not know where that came from, just something I like. One thing I do not like about labs especially in physics is they seem separate.
Lab is a completely different class.
In lecture they would never talk about the lab at all. It would not be hard to say in lab this week you are going to do this and this is how it relates. We are in electricity and optics. Many students experience frustrations with physics. They view physics as impersonal.
