Several students who appeared for the JEE (Main) computer-based test claimed there were ambiguous questions. They claimed there could be errors as they spent a lot of time in cracking the questions.
First part of JEE Main online exam was held on 9th April Tuesday. Reportedly the format of JEE Main online paper was very similar to offline exam, some questions in physics were tricky. Mathematics and chemistry gave relief to most of the students.
Students told that there were around seven debatable questions carrying 28 marks, but as the paper was online no one has a copy of that paper, it is not possible to confirm these errors and students may suffer.
A lengthy and tough physics section, chemistry questions right out of the CBSE syllabus and a relatively easy math section - this was the predominant opinion among most students who took the online JEE mains on Monday April 22, 2013.
There were some unexpected questions too. For instance, some theory-based ones in chemistry and physics were difficult, said students. "A question was asked about the Baker's reagent. I did not know about it, neither did my friends," said Ashish Nagarajan, a student.
Experts are unable to pinpoint the errors as students do not have a copy of the questions. But, the CBSE claimed that question papers will be available to the students after all tests in the online slots are over.
Praveen Tyagi, MD, IITians' Pace, another coaching institute, said, "Several students claimed there were errors in the question paper. The board should have ensured an error-free paper, as even one mark in this highly competitive exams matter. What about students who are at the boundary line of selection for JEE(Advanced)? They will lose out on these marks."
Akshit Gupta, one of the aspirant who attended JEE Main 2013 Online exam on April 23, 2013 told Oneindia Education that the following questions included errors.
Chemistry - Out of syllabus questions (INFORMATION NOT IN NCERT OR IN JEE MAIN SYLLABUS):
Q.1) Name of reaction when phenol reacts with benzoyl chloride to give phenyl benzoate--name of reaction not in ncert or in jee syllabus
Q.2) When small amount of Kmno4 is added to Conc. H2SO4,a green coloured explosive substance is formed.The substance formed is-not in ncert or in prescribed syllabus.
Q.3) Shape of IF6(-) out of syllabus.Steric no. comes out to be 7. Analysis on various sites show that this compond's shape is not well defined.
Q.4) A question on thermodynamics to select incorrect statement but all statements given were correct.
Q.1) A question in which magnetic field was written as coming out of plane of paper. But in figure, it was shown in the plane of paper. Taking magnetic field to come out of plane of paper rendered all options incorrect.
CBSE chairman Vineet Joshi said the 'errors' are based on students' assumptions. "Papers will be available to students after computer-based tests are over. Our experts will verify the claims and, if there are errors, we will compensate students," said Joshi, adding that students need not worry.
