Hii Sonia!
Gautam Buddha University, greater Noida does not offer B.A or BSc course in psychology.
It does offer MSc Hons in applied psychology but, no such ourse at undergraduate level. So, you can apply for the course after completing your graduation.
Hope this helps.
Good luck!

The School of Humanities and Social Sciences offers Applied and Clinical Psychology for eligible Candidates at MA/M.Sc and M.Phil levels. But there is no Psychology course offered at Undergraduation level. So there is no BA/B.Sc in Psychology at GBU. You can check the complete list of courses available at GBU at their page: http://www.gbu.ac.in/academic/academic-programme
