For the benefit of the students, specially the aspiring ones, the question of IIT-JEE, 2003 Screening are also

given in this paper. Keeping the interest of students studying in class XI, the questions based on topics from

class XI have been marked with ‘*’, which can be attempted as a test. For this test the time allocated in

Physics, Chemistry and Mathematics are 25 minutes, 25 minutes and 25 minutes respectively.
