IIMs are one of the best management institutes that offer pgdm/PGPX/PGP/executive MBAs etc which are well aligned with the industry need. You are placed well once taken the course. Graduates from any stream can do these courses Via entrances like CAT.

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 TISS for MA psychology programme because after pg you can get more opportunities
