I took my CHL class in early December. I didn't take a single note the entire class, actually none of the students did. None of us got more than one question wrong on the exam and almost all of us received 100%. But as another poster mentioned, notes are the most significant after class when you sit down and start thinking about all the information the instructor gave you. In a few short weeks or months (if your unlucky with DPS), you will be legally able to carry concealed. That's when the magnitude of the responsibilty you will have for yourself and others sets in and you want to be prepared. That's when I started thinking about the details, did he say 300ft from a school zone or 300ft from a school building. Thats when I wished I had taken notes. I'm still waiting for my plastic and in the interim I've been reading the CHL-16 as well as getting feedback from the forum members, who have all been extremely helpful. I feel I am prepared and I will continue my learning going forward. So take notes or don't take notes but as the others have said don't discontinue your learning after you pass the exam.
