I managed to get 98% by "taking" the online course. I ran it in the background on my PC for a couple of days while making dinner and stuff, studied for about 20 minutes before test time and nailed it, got a handwritten note from the proctor saying I should instruct. No thanks.
Don't waste your time sitting in the class for two days, online is the way to go. If you have a functioning brain you could probably get 75% right now.
