Do you know the main function of freshmen courses? It’s to make sure that every student has the same base knowledge before going into sophomore level courses. It’s giving the students from shitty high school backgrounds an opportunity to catch up with those from private schooling and those from school boards that didn’t provide sufficient challenges. These courses don’t need a higher teacher to student ratio, they just need students to pay attention to the lectures and talk to the TA if they’re stuck.
