manivannan, i think it would be better if you restrict yourself to writing essays on various topics. you have been doing a wonderful job writing such essays.
please leave the job of providing tips for mains and interview to the officers who have succeeded in getting through all these exercises. such tips would be more authentic and practical as they have been tried and tested. in any case the above article of yours is just a verbatim cut and paste from another
upsc website which i dont want to mention here. if i did, the moderator would reprimand me for mentioning a live competetor website.
but i appreciate you for the other wonderful articles you have posted. they are really informative as i also have opted for history. keep posting more such informative articles. thanks.
