 My Experiences, is an interesting post on his journey from the 7th standard till 2022–2023.
 FAQs — one of the FAQs is the following.
Are math olympiads = SOF IMO?
No!! Check my page on math olympiads for more information.

 To quote from this post:
Sophie Fellowship is the gem! It provides such a nice community and so many resources!
Do join OTIS! It is simply so good. Evan is also very kind with financial aid. Moreover, do not be scared of applying! And if there is some financial burden, do tell to Evan.
