Scoring zero in the lab component / Abstaining from lab classes throughout.Makeup and Attendance policies:Make-ups are not given as a routine. It is solely dependent upon the genuineness of the circumstancesunder which a student fails to appear in a scheduled evaluation component. In such circumstances, priorpermission should be obtained from the Instructor-in-Charge (I/C).The decision of the I/C in the abovematter will be final.Attendance: Every student is expected to be responsible for regularity of his/her attendance in classrooms and laboratories, to appear in scheduled tests and examinations and fulfill all other tasks assignedto him/her in every course. A student should have a minimum of 50% of attendance in a course to beeligible to appear for the Comprehensive Examination in that course. For the students under the purview ofAcademic Counseling Board (ACB), the Board shall prescribe the minimum attendance requirement on acase-to-case basis. Attendance in the course will be a deciding factor in judging the seriousness of astudent which may be directly / indirectly related to grading.General timings for consultation:Each instructor will specify his / her chamber consultation hours duringwhich the student can contact him / her in his / her chamber for consultation. (For details see part II)General instructions:Students should come prepared for classes and carry the text book(s) or material(s) as prescribed by theCourse Faculty to the class.Notices:All notices concerning the course will be displayed on the respective Notice Boards.To be announced laterInstructor-in-ChargeDr.R.UdayakumarInstructor’s Contact details: Dr.R.Udayakumar (Course Coordinator) – Academic Block, Chamber No:274 Contact Tel.
