Amongst all the papers i find general studies to be most interesting..as GS has lots of sections like polity,ecenomics..so sumtimes aspirants become confused about how to go for it...
i wrote 2 mains one in 2007 and one in 2009(i didnt take ne attempt in 2008)
n there ws wide difference in GS papers of 2007 and 2009...i got 325 in 2007 mains and 296 in 2009 mains...n m quite satisfied wid my score as it is on expected lines only
I m listing the books/material/magazines i followed:
1)polity : DD basu
2)economy: NCERT,pratiyogita darpan
3)modern india :bipin chandra
4)vajjiram materials and classroom notes
5)current affairs special by wizard
6)india year book,eco survey
7)statistics : i practised prev qs papers within time limit
8)Indian culture:as i had history opt so didnt do nething specific for this
9)geog : ncerts
10)vajjiram materials and class room notes
11)for 2009 attempt i ws in delhi for 2.5 months n i took one mains test series program for gs from sriram although i wrote just 2 tests der i.e economy n modern india bcoz of time constraints bt overall it ws gud
12)hindu,yojana,kurukshetra,frontline,chanakya(won a prize in aug 2002 on the essay of disinvestment of public sector underatkings from chanakya n collected the book list from da toppers' intreviews dat used 2 come der)chronicle,competition wizard + one magazine dat used 2 vary depending on da coverage for the particular month...i.e if sumtime i like CST then i used 2 take dat n if i liked chanakya or civil services analyst i used 2 take dat...
