Best Reference Books for CBSE Class 10 (2027): Subject-wise Recommendations

NCERT textbooks are the foundation of CBSE board exam preparation. No reference book can replace them. But for students aiming for 90%+ marks, or those who need extra practice problems and detailed explanations, reference books serve as valuable supplements.

The key word is supplement. Too many students buy five reference books per subject and never finish any of them. This guide recommends only the best two to three books per subject, explains when each book is most useful, and helps you decide whether you actually need a reference book at all.

Before You Buy: Do You Need Reference Books?

Not every student needs reference books. If you are aiming for 75-85% marks and study NCERT thoroughly, you may not need anything else. NCERT combined with previous year papers covers everything you need.

Reference books become useful when you need more practice problems than NCERT provides (especially in Maths), when you want detailed explanations of concepts that NCERT covers briefly, when you need sample papers and additional exam-style questions, or when you are aiming for 90%+ and want to be prepared for any question type.

If you do buy reference books, commit to finishing them. An unfinished reference book is worse than no reference book because it creates anxiety about "not having covered enough."

Mathematics

RD Sharma is the gold standard for Class 10 Maths. It has a massive question bank organized by difficulty level (Level 1 and Level 2). Level 1 questions cover board exam difficulty, while Level 2 questions push your understanding further. The book is particularly strong for Algebra and Coordinate Geometry chapters. The downside is its size, which can feel overwhelming. Focus on Level 1 questions first and only attempt Level 2 if you have time.

RS Aggarwal is a more concise alternative to RD Sharma. It has fewer questions but they are well-selected and cover all major question types. The explanations are clear and the book includes a good collection of HOTS (Higher Order Thinking Skills) questions. This is a better choice for students who want quality over quantity.

Oswaal CBSE Question Bank is excellent for the final two to three months of preparation. It organizes previous year questions chapter-wise and includes marking schemes, so you know exactly how marks are awarded. The latest editions also include competency-based questions aligned with the new exam pattern.

Recommendation: Choose either RD Sharma or RS Aggarwal (not both) for regular practice, and add Oswaal Question Bank for the final stretch.

Science

Lakhmir Singh and Manjit Kaur is the most popular Science reference book for Class 10, and for good reason. It breaks down Physics, Chemistry, and Biology into simple language with plenty of diagrams. The question bank at the end of each chapter is extensive and covers every type of question asked in board exams. The book is particularly helpful for students who find NCERT explanations too brief.

S. Chand's Science for Class 10 is another solid option, offering detailed theory and a good range of practice questions. It is slightly more advanced than Lakhmir Singh and is better suited for students who already have a basic understanding and want to deepen it.

Oswaal CBSE Question Bank for Science provides the same benefits as the Maths edition: chapter-wise previous year questions with marking schemes and competency-based practice.

Recommendation: Lakhmir Singh is the best single reference book for Science. If NCERT explanations are sufficient for you, skip the reference book and just use Oswaal for question practice.

Social Science

Arihant All-in-One Social Science is the most comprehensive reference book for this subject. It covers all four sections (History, Geography, Civics, Economics) with detailed notes, map work practice, and a large question bank. The book includes timeline charts for History and concept summaries that are very useful during revision.

Oswaal CBSE Question Bank for Social Science is particularly valuable because Social Science questions are subjective, and knowing the expected answer format and length is crucial. Oswaal shows you the marking scheme for each answer type.

Xamidea Social Science is another good option with a clean layout and well-organized content. It includes a mix of objective and subjective questions and is slightly easier to navigate than Arihant.

Recommendation: Arihant All-in-One is the best standalone choice. For students who are comfortable with NCERT theory, Oswaal alone provides enough practice.

English

Arihant English Language and Literature is a solid reference book that covers grammar, writing formats, and literature comprehensively. The grammar section is particularly useful, with clear rules and plenty of practice exercises.

Oswaal CBSE Question Bank for English includes previous year questions organized by section (reading comprehension, writing, grammar, literature) with detailed answers and marking schemes. For English, seeing model answers is extremely helpful because you learn the expected writing style and format.

BBC Compacta English is a well-known reference book that many CBSE schools use as a supplementary text. It has extensive grammar exercises and writing practice sections.

Recommendation: For most students, Oswaal alone is sufficient for English. If grammar is a specific weakness, add Arihant for its grammar exercises.

Hindi

Arihant Hindi A or Hindi B (depending on your course) provides comprehensive coverage with good grammar sections and literature explanations. The book includes practice papers and chapter-wise questions.

Oswaal CBSE Question Bank for Hindi, like its counterparts for other subjects, offers previous year questions with marking schemes. This is particularly useful for Hindi because understanding the expected answer format for literature questions can make a significant difference in marks.

Recommendation: Oswaal is usually sufficient as a supplement to NCERT for Hindi. Add Arihant only if you struggle with grammar or need extra writing practice.

How to Use Reference Books Effectively

Do not start with reference books. Complete the NCERT chapter first, understand the concepts, and solve all NCERT exercises. Only then move to the reference book for additional practice.

Do not try to solve every question in the reference book. Focus on questions that are different from NCERT exercises. Skip questions that are too similar to what you have already solved.

Use reference books for targeted practice. If you are weak in Trigonometry, use RD Sharma's Trigonometry chapters extensively. If you are strong in Algebra, a few selected problems are enough.

Time your practice. Board exams are time-bound, so solving reference book problems under timed conditions is more valuable than solving them at your own pace.

The Free Digital Alternative

In addition to physical reference books, free digital platforms like Padhaao provide chapter-wise practice questions, mock tests, and revision materials that cover the CBSE syllabus. For students on a budget, these digital resources can effectively replace some reference books, especially for question practice and self-testing.

How Many Reference Books Should You Buy?

The honest answer: fewer than you think. One reference book per subject is usually enough. For most students, the combination of NCERT plus one reference book plus Oswaal Question Bank covers everything needed for 90%+ marks.

Buying too many books creates a false sense of productivity. You feel like you are "doing something" for your preparation by accumulating resources, but actual preparation happens when you sit down and solve problems.

Final Thoughts

Reference books are tools, not magic solutions. The best reference book in the world will not help if you do not study consistently and practice regularly. Start with NCERT, add one reference book per subject if needed, and focus on actually completing what you have rather than accumulating more resources.

The students who score highest are not the ones with the most books on their shelf. They are the ones who finish what they start, practice regularly, and revise thoroughly.
