All About School - The Complete Education Forum and Classifieds

My younger brother is studying in business school. I often help him with his assignments and projects even though I know nothing about business and commerce! But hey, that’s when Google comes in handy. Whenever I am looking up something on the internet, I can’t help but notice that almost every topic is listed on Wikipedia. There are dedicated affordable Wikipedia page creator, events, objects and almost every topic of public interest. I often take out most of the required information for my brother’s homework from Wikipedia and well, it has never gone wrong. But still, sometimes I wonder if I should blindly trust this site like this or trust it at all.
Is all the information provided on Wikipedia authentic? Who makes sure that the content is up-to-date?
