Why Some People Didn't Get Invited to the Energy Points Challenge
For the energy point challenge, the reason of not getting the invitation and the chance of signing up is because whoever didn't get the invitation was not over 13 years old. It says type the exact:

"I pledge I am over 13 years old and promise to do my best during this challenge."

That quote might not be exactly the same, but it is similar because I did it from my memory.

Even my age was under, I got invited because long time ago, I wanted a Facebook account. I couldn't get the Facebook account, so I tricked my age and made a Facebook account. I log in to Khan Academy with Facebook, so that why I got in.

*Important*
What I said up there was a guess, so don't blame me if that isn't the reason.
