Practical Syllabus (Semester: IV; Batch: 2014-15)
PRACTICAL-II: Project Work/Home Paper
Max. Marks: 100
Project Work / Internship is compulsory for the University students.
Selection of Home Paper/Project Work is optional for affiliated college students.
The students opted for Home Paper must be assigned a latest topic and the students
have to submit a dissertation (50-60 pages) covering all the latest literature on the
topic assigned. The candidate will be assessed at the time of the conduct of final
practical examination of the semester taking into consideration of dissertation and
viva-voce on the topic chosen for home paper.
