Hi Azhaghu, good question! We had a beta version up and running for a few weeks in the summer of 2012, and then we took the site down for a while to work on making it much better. We consider October 28, 2012 to be our official launch date.

Staff - 4 years ago

Wow ! My B'day is on the 20th ! Haha , I am older than B'ant by 8 days :P

Anyway , thanks for replying ma'am :)

- 4 years ago

So you were born on 20th october $$\huge 2012 \ ?$$

Because you're saying that you're 8 days older than Brilliant !!

- 4 years ago

Brilliant has really been like a boon to me. Until I started solving problems on Brilliant, I used to be weakest in Maths(during 11th). Gradually it has become my strongest subject and now I look forward to solving Maths. I would like to thank the Brilliant community for posting such nice questions. It has been a truly wonderful experience here.

Which age group contributes the maximum part of the users on Brilliant ?

Maybe 14-19

- 4 years ago

You might want to add some more ages as well . $$24 , 30 , 49$$

Just enter Sandeep sir's ,Calvin sir's and Brian sir's names in the search box and check out the number of questions that they have posted !

- 4 years ago

The question was "Which age group contributes the maximum part of users on Brilliant", not questions.

Oops! You got me . Thanks for the catch. Btw , what's your opinion on this question ?

- 4 years ago

Depends on how large a group you want. Otherwise, you could just say $$(0 - 200)$$ age group. Though 13-18 sounds correct.

Thought so too . I started with Skeptical Patriot . I liked the plot , so i have saved it for reading after JEE mains .

For Q4 I think India should be the answer.

- 4 years ago

Yes it looks like India only.!
