MSc-IT bein a new course hs updated syllabi wher u get to learn the latest programming languages bein used these days.. whr as in MCA d syllabi is smwat outdated (atleast dis is d case here in chandigarh)..
d best part f doin MSc-IT is dat aftr completing your 2 years you cn opt for MCA lateral entry prog offerred by sm universities wher u'll b directly admittd 2 3rd year f d prog... so dis way you get two PG degrees in a span f three years..
If previously u'v done BCA/B.Tech(IT/Comp.Sci) i would suggest dat u go fr MCA/Msc.IT... you cn go fr MBA(IT) latr on ..
I'll b givin MCA entrances dis year
