Over 2.5 lakh students across the country on Sunday appeared for the Joint Entrance Examination (JEE) for admission into the IITs in the country.
Adequate arrangement have been made in the Delhi Zone which consists of National Capital Region, Jammu and Kashmir, Himachal Pradesh and Punjab, IIT Delhi Director Prof Surendra Prasad said.
"There are 48,000 candidates in the Delhi Zone, including 33,000 in the NCR itself. In this zone, we have set up 104 centres, including 74 in the Capital," he said.
The test comprises two papers of 200 marks each.
"We have informed the police authorities that in case of need, we may seek their help," he said.
There are seven zones with one zone under the supervision of each IIT where the entrance was conducted.
To ease the exam blues for students, the IIT JEE has decided to change the pattern of test this year, making provision for two papers in place of three.
Each paper consists of questions of Physics, Chemistry and Mathematics.
Earlier, the students had to appear for three papers, one each dealing with physics, chemistry and mathematics. The papers earlier were of two hour's duration.
The questions are of objective type and there is negative marking for incorrect answers, Prasad added. There are over 4,000 seats in these institutes.
