Help on Sophia course

[LongRoad]

I'm new to this site, and I'm not really sure where to post my question. Here it is anyways. 
I have taken 4 courses at StraighterLine, and I know pretty well how to get through a course there. Now, since of the free Sophia courses(till the end of July), I'm taking my first course at Sophia which is Art History 1.
So, for those of you that have taken courses through Sophia, what was your experience like. What tips do you have with getting through a course in a timely manor? Do you take extensive notes? What are the milestones like? 
I just graduated last year from high school/home school, so I'm having to figure out how to learn in a higher education system. Any help/tips will be appreciated.

I kill trees. I print up the PDF for each chapter and write notes on them. These notes are more for clarification for me as my experience is that everything in the Challenges and Milestones comes from the lectures. (There is surely an easier way to download the notes and electronically add notes, but I don't know how to do that.)

I also copy and paste the Challenges to a Word document so I know where I need to study. (The Milestones and Challenges give you green checks when you answer correctly, and, if you answer incorrectly, green checks appear next to the correct answers, and  red "x's" next to incorrect answers.) The exams I've taken allow two hours for their completion. They're open book exams, so even with my compulsion to double-check EVERYTHING, I have enough time. (And don't get me started on how miffed I get with myself with I change a correct answer to an incorrect answers.) One course I took allowed two chances for each Challenge question, and the other allowed three chances for each Challenge. 

As you've probably already read, Challenge questions are weighed less heavily in your grade than Milestones. Oh, and I usually do the practice Milestones and copy and paste them to Word to help me study.

Good luck. If you can, please report back on the course. It's one I'm thinking of taking.
