Candidates and their teachers have spotted multiple "discrepancies" in the answer key to the Joint Entrance Examination (mains) held earlier in April.
Considering this exam regulates admissions to engineering colleges across the country — and serves as a screening round for JEE (Advanced) for the Indian Institutes of Technology — candidates and their coaching-class instructors are worried about some of the answers furnished by the Central Board of Secondary Education on April 18.
One parent has listed problems with as many as four questions in Set C — question 22. "This question is incorrect but CBSE has indicated it's correct.''
The CBSE has declared question 51 incorrect while, according to her, it is correct. Question 53 has "two correct options"; and question 57 has, as per CBSE, only one correct answer while there are actually two. For the question CBSE has itself considered wrong, everyone will get four marks.
"There is a probability question in mathematics in which none of the answers fit but the answer-key justifies one answer. In a physics question, two options are possible but the key mentions only one. Students have sought my counseling but we can only direct them to challenge the answers," said R L Trikha of coaching-class chain, FITJEE.
