Here I request to Calvin sir to please make a class for RMO, INMO and IMO(separately). In these classes please sir make good problems and a forum where we can type the proof of it. Also sir there you can recommend us wikis , books and make videos. Sir this would help most of us to improve our math and help us to do better in RMO(Better than what we will be able to do without your help.)
Also can anyone open classes for Physics and Computer science.
