Is it fine to prepare for UPSC after BA or MA?

Dear Siwangini, If your aim is set to clear upsc than start taking coaching after ba and give your time approx 1 to 2 yrs for preparation .Side by side you can do MA programme in the related specialisation. All the best

yes but u should do Ba(honours) and If you interested in psychology then you can chose Ba (Honours) psychology programme at Sam Higginbotom Institute Of Agriculture Technology and Sciences, SHIATS, allahabad, Uttar Pradesh and prepare for Tata Institute Of Social Sciences for MA psychology programme
