I am about to finish the Penn Foster Composition course, it has been extremely flexible, no proctor neccessary.
It is structured with two multiple choice tests and 4 essays, It should be finished within 3 months, in my case I had to request and I was granted an extension due to a family emergency.
The delivery format is very friendly and feedback from instructors is quick.
You will have the option to use regular mail if you choose to do so.
I believe it is a Pass/Fail at Excelsior to meet the WER requirement.
I liked the price (includes all materials!) the quality and the flexibility.
I hope this helps. Good Luck!
