The University of Delhi is in the process of revising the undergraduate syllabi under the Learning Outcomes Curriculum Framework (LOCF). The B.Sc. (H) Microbiology programme is being revised as per the national CBCS guidelines and LOCF. The Draft of the same is now ready which may be downloaded here. The Department invites all stakeholders to study the draft and submit comments, if any, for consideration by Committee of Courses. The comments may be submitted by email to ranigupta.udsc57@gmail.com or microsdc@south.du.ac.in latest by 31-May-2019.
