This is a very common question!
Firstly check that it hasn’t been answered yet. Your answered questions should appear on your profile page. We will also email you to let you know if we have your email address, but sometimes our emails go into the spam folder.
Secondly, give it some time. Scientists are real people with jobs, they’re volunteering their own free time to answer questions. Scientists will answer all the questions they can, as quickly as they can, but it might take until the next day.
Also, if two students ask the same question then we’ll delete one but put both students’ names on the one we keep. So your name may be there but not your exact words.
If you think your question hasn’t been answered because of a technical problem, please email email@example.com for help.
