Disclaimer: If you are familiar with Linear Algebra, you may love this course. This review is not for those people. This review is for the people who went to the course details, saw that the recommended audience was 'Beginner' level, and decided to give it a try, thinking it involved a low barrier of entry. You'd be thinking incorrectly. Here is why.
Let me start off by stating two things. First: I am terrible at all things mathematics, and wanted to improve my capabilities in this area. Second: This is by far the worst Coursera course that I've taken to date. I put all my effort into not only completing the course, but doing so on time, so that I don't dump more money into a course than completely necessary. With this course, I found myself loathing the prospect of torturing myself with the material, that I kept putting it off. I eventually had to come to terms that I hated this whole experience, and canceled my subscription prior to completing even the first course!
1.) The videos are absolutely useless - Up-to-date on all the latest and great math jargon? Well, you'd better be, or else you'll find yourself Googling terms like a madman and re-watching the videos over and over, just to get a grasp on what is going on. All this is topped off with the instructor talking a mile a minute (does he even breathe?) and making numerous mistakes throughout the videos. This will then prompt you to pause the video you were watching to go search the forums in order to see if the way you were taught to do something in a previous video was incorrect all along, just to find a post that confirms that the video did in fact have an error. Do yourself a favor and skip directly to the practice quizzes. You'll be equally clueless as to what is going on, but you won't have wasted time by watching pointless videos.
2.) I'm assuming the assignments and practices quizzes are in some way correlated to the subject matter depicted in said useless videos in point 1. If there is, then the questions therein are massively beefed up version of the subject. Nothing made me feel quite as stupid as practice quiz 1 of week 4 (this is where I finally gave up and called it quits). The only redeeming factor is that I'm not the only doofus in the room. The student forums are full of equally clueless people.
3.) For the price of $50 a month, I expected this course to house all I would need to ease me into the topic of Linear Algebra. Instead, it feels like I've been thrown into the ocean with cinder blocks strapped to my feet without knowing how to swim. Logically, I started grasping for the life boats that are Khan Academy and YouTube. I shouldn't have to go to external resources if I'm paying money to be taught something, but I did. Even though these external resources helped me better understand the concepts, the quiz material still looked like absolutely gibberish to me. That's when I knew this was no "Beginner" course.
All said, just buy a Linear Algebra text book off of Amazon if you want to learn this topic. It's cheaper in the long run, and coupled with Khan Academy, it'll get you farther. The only reason it isn't a single star for me is the fact that maybe it is beneficial for people who actually like math.
