The M.A./ M.Sc. “Previous” (Mathematics) examination will consist of two semesters, called first and second semesters. Their examinations will be held in the months of December and April respectively. In each of these semester examinations there will be five compulsory papers and one optional paper. Each paper will be of three hours’ duration and of 50 maximum marks, except where stated otherwise. Besides there will be a viva-voce & project work examination of 50 marks in the second semester.

 

Format of the Question Paper.

There will be one compulsory question consisting of 5 parts of short answer type question based on the whole course, with all being mandatory to be answered. Besides, there will be 8 more questions, ordinarily consisting of two parts (a) and (b), 4 questions per part, out of which exactly 4 questions (two from each part) will have to be answered. Thus in all 5 questions will have to be attempted and 9 questions will have to be set. All questions will carry equal marks, except where stated otherwise.
