3 General Instructions a. Please note that the student has to obtain at least 12 marks out of 30 marks in internal assignments and 36 marks out of 90 marks in university examinations. b. Students are advised that improvement in assignment marks is not permitted at a later stage once the student gets the minimum passing marks or more (i.e. 12+ marks). Hence the students are advised to try to score the maximum at the first attempt. c. Assignments should not be copied, should be clear, legible, well presented. d. Illustrate your answer by giving suitable examples. e. Draw graphs or diagrams wherever necessary. f. Students are advised that in case two or more students assignments are too similar in content, nature, the study center Co-Ordinator would at his / her discretion decide on the quantum of marks to be awarded, irrespective of how good the submitted assignments are. It is more than likely that the minimum possible marks (if any) may be awarded to all such involved assignments. g. Students are also advised to quote sources (if any) of data, facts, sketches, drawings etc in their assignments. h.
