My Take
It's not interesting, which means that students are easy to get bored and their attention would move on to other things. The curriculum setting is not clear too.
How I Use It
I was trying to let my young sister open this website and learn math. But, the problem is that the videos it has didn't make learning become a fun thing. I mean it did have a lot of images or something, but it didn't change the truth that it's boring.
