Empty Period or Virtual Class

Hello everyone. I hope you are doing well. I would like some advice for my schedule as I am completely lost on what to do. Also, I would just like to state that I have already taken 13 APs and 4 college courses if this affects anything. Basically, I have requested some classes (AP European History and AP Art History) to take during school but I did not receive those courses. I am wondering whether I should take these courses at the virtual school or if I should leave those two periods in my schedule as empty spots as I am already taking 3 college courses and 2 APs at school. The only problem is that I will not be able to put those two courses on my transcript for Early Action / Early Decision (I think) unless there is a way to say the courses I am taking outside my schedule. Is it worth it to take these two courses through the virtual school or should I just leave it as 2 empty periods. I am trying to go to Emory or Georgia Tech and I am currently in the top 20% of my class according to the class rank. Any advice would be greatly appreciated. Thank you so much.
