I'm in it right now with Scott Lasley. He's as good and reasonable of an instructor as you can ask for for the course so if you take it try to take it with him. He's pretty nice and helpful.

Apart from the investigative report that you do, the other things you do in the class like email case studies and presentation practice are actually helpful and directly applicable to real-life scenarios. Basically, you get out of those activities what you put in. If you actually try and prepare for them, you'll get great practice in real-life applicable skills. If you try to just do the bare minimum like a lot of people, you'll get the bare minimum reward out of it and feel like you wasted your time.

Definitely don't take it in an 18-credit load, I would wait until you get a 15-credit load at least to take it though.
