Brainly.com is using a new trend in education and the world wide web,
called social learning or school crowdsourcing. Students use the internet to
make solutions to their homework by co-operation.
This is really great. Once you have registered, quick and free, you can then
either help other students by answering their questions, or you can put in your
own question and what for someone to answer it.
I am really amazed at how quickly the questions get answered.
