CBSE Class 10 Syllabus 2026 for First & Second Phase | Complete Subject-wise Syllabus

Garima SihagUpdated on 20 Sep 2025, 04:16 PM IST

The CBSE is implementing a two-exam policy for Class 10 to reduce pressure and provide flexible opportunities to students. So, most of the students are confused about the CBSE 10th syllabus. They want to know whether the CBSE syllabus for the first and second phase will be the same or if it will be divided between both terms. They should know that the CBSE first phase (February–March) and the CBSE second phase (May-June) exams will cover the full syllabus. There is no syllabus bifurcation between the two phases.

CBSE Board 10th Second Phase Syllabus 2026

CBSE has introduced the dual-exam system to reduce exam pressure by allowing students two attempts in one year. The First Phase is mandatory, while the Second Phase is optional, aimed at improving performance in up to three subjects. The CBSE 12th syllabus remains unchanged, requiring the same preparation for both phases. The above syllabus is the same for the CBSE 10th phase 2 exams.

CBSE Board 10th Syllabus 2026: First Phase & Second Phase

Internal assessments and practical evaluations will continue as a single evaluation per academic year, unaffected by the two-phase system. The new system enables students to prepare for their exams using the complete CBSE Class 10 syllabus in a single instance. If the performance in the first phase is not as good as students’ expectations, they have a second opportunity to retake the exam without having to study new material. This second attempt provides a genuine chance to improve the scores without the added pressure of an altered curriculum. Additionally, CBSE ensures that the question patterns and marking schemes remain consistent across both phases.

Hello

You asked about Class 10 sample paper board exam and most important questions. Practicing sample papers and previous year questions is one of the best ways to prepare for the board exam because it gives a clear idea of the exam pattern and types of questions asked. Schools and teachers usually recommend students to solve at least the last five years question papers along with model papers released by the board.

For Class 10 board exams, the most important areas are Mathematics, Science, Social Science, English, and Hindi or regional language. In Mathematics, questions from Algebra, Linear Equations, Geometry, Trigonometry, Statistics, and Probability are repeatedly seen. For Science, the key chapters are Chemical Reactions, Acids Bases and Salts, Metals and Non metals, Life Processes, Heredity, Light and Electricity. In Social Science, priority should be given to Nationalism, Resources and Development, Agriculture, Power Sharing, Democratic Politics, and Economics related topics. In English, focus on unseen passages, grammar exercises, and important writing tasks like letter writing and essays.
