Of course, the new Brilliant is quite technological advanced and open-to-all kind of an arrangement where we can solve any problem and get constant points, but it seems completely haphazard to me. There is no systematic approach that can be taken. I will request the administrators to bring back the series of 5 questions for each level that can be seen and solved one after the other may be in a separate location in the website.
Thanks in advance. Regards, Sayan.
