If I had another option to chose from I might not complain, but since our instructor will ONLY let us watch your vids, I have to say: while the information is helpful, you tend to add A LOT of unnecessary fluff to your examples. I'm sure you're trying to be thorough in your explanations, but if someone doesn't understand the basic idea of how to work a problem, adding secondary anecdotes to an already confused brain just makes one want to shut down for the day. I shouldn't have to fast forward 2 minutes every video, just to get to the part where you actually work the problem! Another person commented below saying they were confused about how or why you chose a random number to plug in. These are important points that should be acknowledged in the videos!! I'm sure you do your best, but these vids are the examples were being given in introductory pre-calc...nobody in my class is familiar with any of the work put in front of us. It's one thing to ask students to be self-learners, but we're talking super green, barely out of high schoolers here, who don't even know HOW to study properly, in the INTRODUCTORY class...
