What is antecedent river? by google I understood is river which does not changes it path due to its eroding capacities. Then how Kosi is called as antecedent when it changes its course causing floods in bihar?

@EUROPOL Thanks...According to class 11NCERT Kosi is antecedent river. by antecedent we mean below
  • "Streams which maintain its path even after the geological upheavals by cutting across the mountains & ridges"                                                                                                                                                     

But Kosi is famous for changing its path. Then how to say as antecedent. Else for MCQ I will just remember it is antecedent and its definition and will move on.

@EUROPOL Okk.. They are talking in context of upheavals.. Rising of Himalayas (geological upheaval) didn't have impact on Kosi..Thanks

Is there anyone who is attempting mocks in 4 rounds?

I am trying it but facing difficulties. From 1st round to 4th round bubbles are black. How to estimate accuracy then? Do you bubble with different colors for that sake but it wont be possible in Classroom mocks and on 'the actual day'.

Please help how to execute 4-3-2-1 strategy..

@DramaticAdmiral I agree but most of cleared people have suggested to attempt in rounds. I also feel 3 rounds should suffice with Sure then 50:50 and questions were one option eliminated.

@Celeborn Thanks.. I will also try this. Marking number of round on question paper itself. & yes Its time consuming. finding accuracy and then reading solutions take a lot of time

@AzadHindFauz @Upsc_2020 can you list which are constitutional rights available and which legal rights available?

these days they are asking such questions. How to tackle? Art 300 A is there in constitution but they say it is legal right. Even answer key changes from institutes.

Cannot find any reliable/updated compilation of  mineral resources and their largest producer/s(in India as well as worldwide). Created my own list for quick revision from various sites but not sure of how accurate my drafted information is. Please have a look and point out if there is/are any incorrect info in this; would be of great help.

The red star indicates largest producer.


Mineral Resources.pdf


P.S. If anyone has made a summary of Indian Minerals Yearbook 2019, kindly share please.



Thanks for the list. I remember last year there was a thread where people posted about important topics and put up the relevant materials for prelims. Can someone post the link of that thread as I tried to search for it but could not find it.

Is there any such file pointing out largest state in rice wheat sugarcane and all like this ... such compilation will be saviour.. also how are you preparing eco facts like last 5th in Gdp in terms of ppp

@PursuitofHappyness I want to condense such data at one place but has not done till now. It is scattered here and there from CA, test series etc.
Previous year someone shared the evernote file regarding such data of economics. But I am not able to relocate that thread where such resources were posted.


Yes .. it's scattered and becoming difficult to remember as in haphazard state.. Mrunal sir k notes me dekhna padega 

Also if some one has prepared economy facts please share..

Q26 My bad. Not the first silly mistake I committed in this paper.

Q37 I see.

Q58. So, what did you mark for this?

In 58, one need not go that deep. Simply think along the lines of western vs Indian secularism. When there is no strict separation of state and religion, then assuming religion is merely a private individual matter does not add up. 

Source of questions ? Is it pyq??

Is it D ? Bcs prior to that it was oreintalist vs angelist tussle over patttern of education. Macaulay and later wood adopted anglist approach of introducing rationalism. Infact wood I think looked at Indian edu as inferior
