open periods are very common at our school-- not even by choice-- just scheduling constraints. To answer your question: It depends on info you have not provided like What Colleges? What Major? Etc. Your schedule does look a little non-standard for a junior. Not sure what “College Level” means if its not AP . Do you mean “College Prep” level? If so, that just means not remedial. Really it all depends on what schools you are targeting and your others stats. The choice to have study hall over
Psych is not a huge deal but these others things do matter.
It shouldn’t impact anything towards your college acceptance. You have a great schedule as you are taking AP and college level classes. When I was in high school, I would take a study hall every year because I would have my credits required so I would have time to complete my assignments and it really helped me. So I would say taking a study hall would really help especially since you got quite a load there with your schedule. Best of luck!
