Counselor won't let me take AP classes online in addition to my 6 classes?

So in GA, there is GAVS, completely straightforward place to take your online classes. I requested to take AP psychology AB and AP government U.S. online. I’m a junior, I have my time to prep for SAT so that doesn’t conflict with my schedule. I’m also taking 2 AP’s right now…Comp sci, and Apush both of which I have an A in, the rest of my classes are on level including math. Is there anyway I can convince her to let me take those classes? I don’t procrastinate/slack off, actually do my work and have a okay GPA, (3.7).

I mean her reason for denying it could be because its an AB class and AP + I want to take AP Government, but its like a 4.5 month course so the workload is going to be nothing new since I am taking apush which is just reading/writing.
