ICSE Chemistry Exam 2026 Tomorrow: Important Topics for Science Paper 2, Students Must Revise

Students appearing for ICSE 10 Chemistry exam 2026 tomorrow from 11 AM to 2 PM. They should focus on revising important chapters and previous years’ ICSE Chemistry questions for better marks in exam.

ICSE Chemistry Exam 2026 Tomorrow

ICSE Chemistry Exam 2026: Council for the Indian School Certificate Examinations will be conducting ICSE Class 10 Chemistry exam (Science Paper 2) tomorrow. Chemistry is considered one of the most scoring subjects in ICSE board exams, provided students revise important concepts, reactions and formulas. They must focus on high-weightage chapters, chemical equations and numerical problems to score better. A quick revision of important topics and concepts can help students perform better in ICSE Chemistry board exam.

ICSE Chemistry paper carries 80 marks and is conducted for two hours. The class 10th question paper is divided into two sections:

• Section A (40 marks): Compulsory short-answer questions, including MCQs, fill-in-the-blanks, match-the-following, and diagram-based questions.
• Section B (40 marks): Students must answer any four out of six descriptive questions from different chapters.
• Questions in Section A usually cover the entire syllabus, making thorough revision essential.
