im interested in doing b.a. in psychology from lady sri ram or jamia milai,but i don't have any idea about admission or entrance exams...

For admission in JMI u have to take up the entrance test for the same.following is the exam pattern http://jmi.ac.in/upload/programme/ets_fss_ssg_i_ssg_ii.pdf and for DU there is a cut off. if u fall in that u r in. bt remember admissions r on first come first serve basis.
