"Some one markers, sub parts of three marker and five markers were a bit confusing," Ms Sapra said.
She also said that, in inorganic chemistry some word problem questions were unconventional.
"Students who had followed the instructions and had studied, every line in the NCERT book, would have attempted the paper well. Many questions were brain ticklers ensuring that students give a thought and understand before answering," she added.
Overall level of the paper was from expected topics barring a few and it required a lot of concept clarity, said Ms Sapra.
Ms Sapra also said the value based question was in today's CBSE Chemistry paper was attemptable to all.
"Though it was as per CBSE blue print but not too many students will be able to score cent percent as sub parts of few questions are tricky to nail. Scoring more than 95 percent marks would be quite challenging," she hoped about the scoring part.
'Overall question paper was satisfactory but few short questions were twisted,' said Soumya Ranjan Mohanty, PGT Chemistry, Mother's Public School, Bhubaneswar.
Overall it is a 'fair' paper except few tricky questions which were time consuming. Again, there can rarely be a Chemistry paper which won't require a good deal of time to attempt the questions; practicing sample papers was therefore suggested before the exams.
While teachers say that scoring good marks won't be a constraint, CBSE class 12 Chemistry students are worried over few HOTS (High Order Thinking Skills) questions. Majority of the questions were from NCERT text book, except few numerical questions. There were questions which required two formulae and this has confused students.
'Most of the questions where bit tricky and indirect. Especially the 3 Mark questions from Section C,' reads the petition filed by the students.
Lesser gap has also been cited to be another reason; students say they didn't get much time to revise for the exam. 'Considering that we only got a single day to revise the portions before our exam which is yet another reason which made this paper tough,' adds the petition to CBSE started online.
