Wrong questions, more than 1 right answer fox JEE students

Mumbai: The 2018 edition of the Joint Entrance Examination (JEE-Main) was an easy paper as compared to many in the past. But what left students puzzled were wrong questions in the physics section and other questions which had more than one correct answer.

A total of 10.43 lakh candidates took the exam in 112 cities in 1,621 centres. While 6.5 lakh were boys, 2.7 lakh were girls and three transgenders. Students also appeared for the exam in eight cities abroad.

Most students said the exam was simple, with physics being the toughest and maths being time-consuming. Praveen Tyagi MD of Pace IIT & Medical, said, “In physics, two questions were ambiguous.” Other faculty said chemistry had one question with two correct answers.

In physics, there were 17 questions from class 12 syllabus and 13 from the 11th standard syllabus. “This section had four difficult questions, 20 moderate questions and six easy ones. Initial assessment suggests none of the options of Q6 set B was correct,” said Rajshekhar Ratrey, VP Educational Content, Toppr.com.

In chemistry, experts said there were three difficult questions, 17 moderate and 10 easy ones. Students said there were two correct options in a question on alcohol phenol. Another question on Lewis acid could also have two correct answers, they said.

There were 30 questions each in maths, physics and chemistry with marking scheme of four marks for right answer and for each incorrect response, one-fourth of the total marks allotted to the question would be deducted from the total score.

“The paper is balanced and is set from CBSE syllabus of Std XI and XII. But, as expected, many of the questions were conceptual with some needing analytical skills,” said R L Trikha, director FIITJEE.

Dilip Vaidya, director academics of ICAD, said, “Unlike last year, physics seems to be very lengthy due to involved calculations. It had only couple of questions which required no calculation. Many questions had very close options or close-range options, which required very precise calculation. This made physics further difficult. Only those with high numerical ability will survive in this part.”

Experts at coaching classes pegged the cut-off around 80 of 360. Cut-off for common merit list in 2015, 2016 and2017 was 105,100 ,81respectively. TNN
