Most of the engineering aspirants who appeared for JEE (Main) on Sunday said that they found the mathematics section “tricky and lengthy“. Many also said that the difficulty level of the paper was slightly more than last year.

Teachers from coaching institutes said that the cut-off to be eligible for JEE (Advanced) is likely to be around 100 (plus or minus 5) out of 360 this year.Last year it was 100. The topper's score may be around 345350, said experts. About 10.2 lakh had registered for the test.

At least three questions in the paper were ambiguous or from beyond the scope of the NCERT syllabus, claimed students and teachers. If these ambiguities are confirmed, around 12 marks will be at stake.

“One question in physics is outside the JEE (Main) syllabus and one has two correct answers. Many students found it hard to complete the mathematics paper in the given time,“ said Vinay Kumar, MD of acoaching institute. “Last year, mathematics and chemistry were on the easier side and physics was difficult. This year, many students found the mathematics section difficult.“

Kumar added that question 12 in paper code B had two right answers and question 27 was beyond the scope of the textbook. He added, “For the last two years, CBSE has not considered such ambiguities while evaluating students.“

Ranjeet Iyer, an aspirant, said that mathematics was not only tricky , but he was unable to attempt all questions as it was lengthy . RL Trikha, director of another coaching institute, said, “In set D, question 28 of mathematics was controversial and a few questions were lengthy . In physics, question 34 and 54 were tough and required analytical ability beyond NCERT book,“ said Trikha.

While the answer key will be released online from April18 to 22, the result is likely to be out by April 27.

The IITs pick up 2.5 lakh candidates from JEE (Main) under various categories to appear for JEE (Advanced).
