I have tried variations of confirmed answers (for questions 1-10). I just started, so can't confirm for 11+, but I suspect it should be the same.
I can confirm:
- correct answers are NOT case sensitive, e.g. "JOURNAL29" is the same as "journal29" and "Journal29". So there is no requirement to submit in all caps or all lowercase, as the correct answer will be the same.
- spaces do matter! e.g. If "Mad Max" is correct, then "MadMax", "_Mad Max" or "Mad Max_" is incorrect. (underscore symbol used as emphasis). Be careful not to add an additional space following an autocorrect.
- there are no special characters. Just letters and numbers so far.
