The basics are very, very good: the explanations, UI, questions, graphics, etc. But for the cost of the subscription, I expect more. For example, it lacks the ability to easily review past information. Yes you can take notes, and I do, but that negates the concept of learning on the go, whenever you have a moment to do so. Learning a little at a time, it is easy to forget some of what you’ve already done. Yes, that information is contained inside of the lessons and you can go back and look at that lesson individually. But, the courses need to have an ongoing summary review of information you’ve already covered, like a student would in a notebook. It would also be helpful to have a quiz of randomly selected information you’ve already covered, like Duolingo provides.Secondly, and most frustrating, is that in the last year that I’ve subscribed, courses have disappeared. Specifically “Chemical reactions” I started it and needed to pause to focus on other things and now when I’ve gone back, it’s been removed. I mention this one specifically because I still have my notes, but I recall there being other similar college level courses. A lot seems to have been removed. What initially attracted me to Brilliant was being able to review many of my undergraduate college courses like chemistry, math, and physics. Brilliant say content is continually being added but nothing abut it being removed.
Thanks so much for your detailed feedback—we’re glad to hear you value Brilliant’s approach and presentation. We understand the importance of easier review tools and consistent course availability. Your suggestions are insightful, and we’ll share them with our team as we continue to improve the learning experience.
