Can somebody pleas help me? Since 2 weeks I'm stuck and I can't take any exam. I have to take biology, General math 2 ect but the program won't let me! This is very serious for me can somebody pleas help?

Guys this is very important to me.

I can not take my biolody, general math 2, history, physical science, literature and the high school elective exams.

I can't even click on the take exam button.

I've send several email but with no respond.

I'm working really hard to get my diploma as soon as possible so I can go study abroad and this is holding me back.

Can someone pleas help?
