Took 2015 CSM with history optional (total self study without any coaching , test series or any writing practice and seems the position will remain same in the future also) and scored a meager 180(paper1+paper2).
Now thinking of taking PSIR as the optional . So my queries are :
1).For my situation (no coaching , test series) , is PSIR an appropriate optional for self study ?
2).Based on the previous years , is it more scoring than History ?
3).Please recommend me some books for both the papers.
4).How much approx time would that take to complete the entire syllabus ?
Thanks in advance .
