Considering around 60+ questions were from PYQs and question bank, the average score is expected to be higher this year. It is likely to enter the 90+ range.
Numericals were heavily centered on Solid State and Thermodynamics, solid state, solution, and d and f Block Elements.
Inorganic Chemistry was very "balanced." Questions like identifying Promethium as the radioactive lanthanide and Zin having the highest ionization enthalpy in the 3d series were asked. Coordination chemistry focused on Linkage Isomerism, a standard but vital concept.
- Change in initial energy
- Radius of copper atom
- Calculate the osmotic pressure of solution
- Calculate magnetic moment
- Calculate the work done on oxidation

Numerical questions in Maharashtra class 12 Chemistry paper primarily appeared from Chemical Thermodynamics, Electrochemistry, and Solutions.
Yes, section C and D had some numerical questions. Students were required to write complete, balanced chemical equations along with the names of reactants and products to secure full marks.
According to initial student feedback, Section C (3-mark questions) was the most challenging one. Students were to solve numerical problems and log tables.
No wrong question has been reported as of now. However if any question in today’s paper is found to be technically incorrect or out of syllabus by the board's expert committee, "full marks" (grace marks) are usually awarded to all students who attempted that specific question.
You must secure a minimum of 35% aggregate (combined theory and practical). Since the total marks is 100, students need at least 35 marks in total.
To estimate the score, students can compare their responses with the unofficial key using this 70-mark theory distribution:
- Section A: 1 mark for each correct MCQ and VSA.
- Section B: 2 marks for each correct short answer (any 8).
- Section C: 3 marks for each correct short answer (any 8).
- Section D: 4 marks for each correct long answer (any 3).
- Most students felt the paper blueprint aligned closely with the previous years' trends.
- There was slight anxiety regarding the calculations in Section C.
- Many planned to tackle the MCQs and Section D (Long Answers) first to secure high-weightage marks.
The paper was of moderate level. Students have given mixed reactions as of now. According to Priya Shandilya “the paper was as expected, the section C and D were more lengthy and took the majority of time.”
The students first response and exam analysis will be updated as soon as the students come out of the examination centre. Stay tuned to get LIVE Updates!
