There are others on the forum that know more than I do on this stuff! However, looking at my rising senior’s transcripts for grades 9-12, there is no mention of study hall- even though he took it all three years. They only have the classes he took for credit or that go towards graduation requirements. I don’t know if that is a common thing. I can see it potentially being a negative in that other kids in his school maximized their course load with honors and AP classes rather than taking a study period. So, even with 4.0UW/ 4.6W- he is ranked 15th in his class. The flip side is that he used that time to stay on top of his studies, and also did volunteer tutoring during study period. This is a long winded way of saying it is not necessarily a bad thing to do, but there is some potential impact. Others may have a better idea than I do on how colleges perceive it.
