Did we miss something on diversity?

Research shows a connection between kids' healthy self-esteem and positive portrayals in media. That's why we've added a new "Diverse Representations" section to our reviews that will be rolling out on an ongoing basis. You can help us help kids by suggesting a diversity update.

They will delete you question if they don't like it.

I took notice that the electronic course explains some circuits differently then I learned in college. And when I asked them about it somebody on here deleted my question. And now they won't even acknowledge me or my question anymore. I thought this was a good site, but after this course I don't really recommend this until they get their theory right.

I was stuck on a problem that made me think. I kept trying and finally gave up. Then it tells me the answers in a poorly explained way AND doesn't give me any tips. Don't bother.

Too much consumerism
