Online university with exams, projects, flat rates

[ArboristFlames]

Hi,

I'm wondering if anyone is aware of any online accredited universities that are primarily exam or project based, or have lots of courses that are exam or project based, and charge flat rates (like a fixed price for a whole semester within which you can take as many courses as you want)?

I'm looking for a school that provides grades too (i.e. not pass fail).

When I say exams or projects, I mean as opposed to essays for example. 

So even though they're flat rate per semester, WGU wouldn't work because it's pass fail, and UMPI wouldn't work because it's primarily essays.

Thankss!!
