No, CISCE will not release any official answer key for ISC exam 2026. Students need to rely on unofficial keys to assess their performance.
GMU subject-matter experts have analysed the multiple-choice questions and provided the correct responses to the questions asked in the exam. Students can compare their responses with unofficial keys to analyse performance.
Students eagerly awaiting to analyse their responses with the answer key have to wait some time. Our subject experts will analyse and provide the unofficial keys by 6 PM.
As per Namita’s response on the Maths paper, though the question paper was balanced, she found the Calculus sums a bit tricky and challenging.
According to some students, the Mathematics paper was of a moderate level. The objective-type questions were a bit tricky but manageable.
As reported from exam centres, the exam has been successfully concluded with no incidents of paper leak or cheating. Invigilators are collecting answer scripts of students.
Students are now anxiously solving the questions left unattempted. As only 30 minutes are left, we advise that students complete their paper and keep at least 15 minutes for revision.
With just one left for the Maths exam to conclude, our correspondents interacted with some Physics teachers present at the exam centre. According to them, Maths has always been considered challenging; so this year we can expect it to be moderate to difficult. However, a complete analysis will be possible only after the exam is over.
With around 1.5 hours since the exam started, students are expected to move to Section B or C as per their preference. We advise students that they should choose the section easier for them.

- Dot Product: a.b= |a| |b| cosθ
- Area of Triangle: ½|axb|
To curb incidents of paper leak or cheating, CCTVs are checked properly at all exam centres. Students will be properly verified before being permitted to enter the exam centre. Anybody carrying prohibited items will be disqualified from taking the exam.
Teachers from Delhi-based ISC schools advised students to focus more on calculus as it carries maximum weightage. Per past year paper analysis, Section A, a compulsory section, prominently features definite integrals, derivative applications, etc. So, students must brush up on their preparations for Calculus.
As per the CISCE schedule, ISC 2026 Maths exam will be held today, March 9, in pen-and-paper mode across 100+ test centres in India from 2 PM to 5 PM.
