Answer:
Know the Instructions before setting Mathematics exam paper setting.
1. The question paper must be prepared based on the individual blue print without changing the weightage of marks fixed for each chapter.
2. The question paper pattern provided should be adhered to.
Part A : 10 compulsory questions each carrying 1 mark;
Part B : 10 questions to be answered out of 14 questions each carrying 2 mark ;
Part C : 10 questions to be answered out of 14 questions each carrying 3 mark;
Part D : 6 questions to be answered out of 10 questions each carrying 5 mark
Part E : 1 question to be answered out of 2 questions each carrying 10 mark with subdivisions
(a) and (b) of 6 mark and 4 mark respectively.
(The questions for PART D and PART E should be taken from the content areas as explained under section V in the design of the question paper) 3.
There is nothing like a single blue print for all the question papers to be set. The paper setter should prepare a blue print of his own and set the paper accordingly without changing the weightage of marks given for each chapter. 4. Position of the questions from a particular topic is immaterial.
5. In case of the problems, only the problems based on the concepts and exercises discussed in the text book (prescribed by the Department of Pre-university education) can be asked.
Concepts and exercises different from text book given in Exemplar text book should not be taken. Question paper must be within the frame work of prescribed text book and should be adhered to weightage to different topics and guidelines.
6. No question should be asked from the historical notes and appendices given in the text book.
7. Supplementary material given in the text book is also a part of the syllabus.
8. Questions should not be split into subdivisions. No provision for internal choice question in any part of the question paper.
9. Questions should be clear, unambiguous and free from grammatical errors. All unwanted data in the questions should be avoided.
10. Instruction to use the graph sheet for the question on LINEAR PROGRAMMING in PART E should be given in the question paper.
11. Repetition of the same concept, law, fact etc., which generate the same answer in different parts of the question paper should be avoided.
For Example of Probability questions asked .
Probability: Problems on Bernoulli trials and binomial distribution.
For example: a. A die is thrown 6 times. If “getting an odd number” is a success, what is the probability of (i) 5 success? (ii) at least 5 successes? b. Five cards are drawn successively with replacement from a well shuffled deck of 52 playing cards. What is the probability that (i) all the five cards are spades? (ii) only 3 cards are spades? (iii) none is a spade? c. The probability that a bulb produced by a factory will fuse after 150 days of use is 0.05. Find the probability that out of 5 such bulbs (i) none will fuse after 150 days. (ii) at most two will fuse after 150 days.
Linear programming questions.
Problems on linear programming. For example: a. A corporative society of farmers has 50 hectare of land to grow two crops X and Y. The profit from crops X and Y per hectare are estimated as Rs 10,500 and Rs 9,000 respectively. To control weeds, a liquid herbicide has to be used for crops X and Y at rates of 20 litres and 10 litres per hectare. Further no more than 800 litres of herbicide should be used in order to protect fish and wild life using a pond which collects drainage from this land. How much should be allocated to each crop so as to maximize the total profit of the society?
