Testability
Going the IT way

Established in 1982, the department of computer science at Delhi University is a premier institute imparting quality education. It was the first to offer the three-year master in computer applications (MCA) degree to meet the growing demand for personnel in the IT industry. Over the years, the department has largely contributed to the field of computer science/information technology and has earned the reputation of being a centre of excellence in computer science education, training and research. Since its inception, the department has been consistently evolving and is today widely acknowledged as one of the leading IT educational institutions in the country, the status being the result of conscious efforts from the beginning.

Combining high academic credentials with practical experience, it has managed to forge a strong presence in the IT industry. Apart from MCA, the department offers PhD and MSc in computer science.

The notification for the course is published in April. To procure the application form and information bulletin, you have to send a demand draft of Rs 300 to the registrar, University of Delhi, payable at New Delhi. The last date for receipt of application forms is in May. For more information, write to: Department of Computer Science, Arts Faculty Extension Building, University of Delhi, Delhi 110 007 or call 011 ' 2766 7725-1336 or log into www.du.ac.in

Eligibility

You should be a graduate under the 10+2+3 scheme with 50 per cent marks or have a masters degree with 50 per cent marks with one paper in mathematics and another in either computer science/statistics/operational research.

Entrance exam

The entrance exam is held in June at Delhi.

Pattern of exam

The test is objective-type and of three hours duration. You will have to answer approximately 200 questions on maths, reasoning and statistics with a focus on geometry, calculus, algebra, matrices, probability, and logical ability. The questions are usually based on BSc-level higher maths. The section on reasoning includes questions on interpretation of data, problem-solving, flow charts and algorithms, number system, binary, octal, hexadecimal, truth values, logical operations, logic functions and their evaluation. Logical thinking and a good grasp over maths and physics make it easier to qualify in these entrance tests. Shortlisted candidates are called for an interview.

How to prepare

For maths, you can study from books on algebra and calculus by D.F. Saxena, trigonometry and coordinate geometry by Verma as well as books by Dasgupta published by Bhartiya Bhawan.

The questions on reasoning are not difficult to crack, though they need some amount of practice. Guide books by Edgar Thorpe and R.S. Agarwal can sharpen your reasoning ability.

For statistics, you can prepare from books like Fundamentals of Statistics (Part 1 and 2) by Goon, Gupta and Dasgupta, Principles of Statistics by K.L. Gupta, Mathematical Statistics by Sancheti and Kapoor and Statistics by Ellhense. Practise questions and attempt as many different problems and equations to develop a competitive edge.

sample test paper

Maths
If X and Y are two independent variables with variances 36 and 16 respectively, then the coefficient of correlation between U=X + Y and V= X-Y is :
a) -5 /13 b) 5/13 c) 2/3 d) –2/3
lf(x) = (2 – sin 3x) –1 . Its range contains T where T is :
a) [ ½,1] b) [0,1] c) 2/3,3 d) [1/3,2]

Reasoning
A,B,C,D and E play a game of cards. A says to B “If you give me three cards, you will have as many as I have at this moment while if D takes five cards from you, he will have as many as E has.” A and C together have twice as many cards as E has. B and D also have the same number of cards as A and C taken together. If together they have 150 cards, how many cards has C got'
a) 28 b) 29 c) 31 d) 35

Statistics
Consider an ellipse with center O and major and minor axes 2a and 2b respectively. Let P be a variable point on the ellipse and N be the foot of the perpendicular drawn from O to the tangent of the ellipse at P. Show the maximum possible area of the triangle OPN as (a 2 – b 2 ) / 4.
