Well, in my university's intro programming class, there were a couple hundred people. Grade-wise, the unit tests said it all. You didn't get personal feedback unless you asked for it. The test framework would email you the test cases and what your output was versus the expected, so a lot of times you could figure out your mistake (or bad assumption) without asking the professor. The professor would have the grading details on the whole class so if we missed a lot of points on a particular problem, they would concentrate on that for a bit. If you needed personalized feedback, you could ask the professor questions after class, at office hours, at the discussions section to your TA, or at the TA's office hours. There just wasn't personalized feedback based on your assignments.
