Dear friend, You can find the previous years question papers of psychology on a site www.iasexamonline.com. The site is a storehouse of information about IAS Exam. Here you can find previous years question papers of most common subjects, syllabus, lots of resources for your preparation of many subjects like psychology for upsc, GS, essay and other subjects in its E-library section. It also has blogs, forum, online test etc.

 

I can suggest you another site that is exclusively devoted to the preparation of Psychology for UPSC exam. The site name is: www.psychologyforupsc.in. Here you can get lots of information about psychology for UPSC optional.
