This is the first time I've heard of such a messed up lecture. And it's even paid... The lecturer is clearly stated to be a technician, but I doubt if he really has the qualifications of a technician. If there's anyone who's thinking about taking the lecture, I really want to pack a lunch and follow him around to talk him out of it. (I wanted to give him 0 stars, but it said to enter a blank space, so I had no choice but to give him 1.)
