When a student is promoted from Class 5 to 6, there is a considerable change in the mathematics curriculum as far as the CBSE Class 6 syllabus is concerned. Due to this fact, students are likely to face various problems in understanding the concepts just introduced to them. Students may need to understand the significance of the different reference books available to grasp the tedious concepts with relative ease and comfort. Students select either RD Sharma or RS Aggarwal’s book for reference. They develop a concrete understanding of the cumbersome topics and solidify the understanding related to a particular concept. Generally, the CBSE curriculum emphasizes the clarity of concepts and a solid understanding of the concepts mentioned in the NCERT textbook. NCERT textbooks are indeed more than enough for the basic preparation of Class 6 exams. But additional practice will be beneficial for the students in the long run. You will find the various advantages of both books – RD Sharma and RS Aggarwal below along with the specific set of disadvantages.Â

The advantages of using RD Sharma for reference and additional practice include:Â

- There is an abundance of illustrative examples related to each concept in this book. Due to the well-explained examples, students can easily relate to the situations efficiently and also gain familiarity with the basic idea behind the real-life scenarios. There are more than enough questions available in the book for practice and conceptual clarity. So, the students must choose this book when they have a lot of time in hand for preparation.
- A lot of practice questions are dedicated to particular sub-topics as well as the main topics. The main idea behind using this book is to practice regularly and rigorously. Students need to manage their time judiciously to complete the whole syllabus within the desired time.Â
- Each chapter in this book has a separate section containing the higher-order thinking skills questions. As the name suggests, you’ll need to think out of the box to solve these questions let alone reach the correct answer. There is more than one approach to determine the correct answer to any question. Practising RD regularly will help you redefine the approach to get the correct answer quickly.Â

The disadvantages that come along with using RD Sharma for reference are:Â Â

- RD Sharma is a bulky book, both literally and figuratively. Students may be apprehensive of using this book given its hulking length and volume. As it is said that one must not judge a book by its cover. This saying contrasts the case of RD Sharma. Many students don’t dare to refer to this bulky text just because they are afraid of the volume of the book.
- Even though this book contains a lot of practice questions, RD Sharma cannot be referred to for last-minute preparation because of its extensive nature of explanations. Students will require a considerable amount of time to practice the questions. Thus, practice from RD Sharma will not prove to be time-efficient because of the lengthy and repetitive nature of the book.
- It is a plausible observation that RD Sharma’s book has several extremely difficult questions that can be skipped from the examination point of view. Since a student has to prepare according to the syllabus provided by the CBSE, additional practice from this book will not necessarily prove advantageous. To finish the preparation as per the schedule, it is essential to stick to the topics mentioned in the syllabus.Â Â Â

If we talk about the next available alternative to RD Sharma, the book authored by RS Aggarwal is also used for extensive preparation by students for their respective examinations. There are many benefits of using the RS Aggarwal Solutions Class 6. These can be discussed accordingly:

- RS Aggarwal is comparatively brief and compact concerning its counterpart RD Sharma’s book. Due to the concise nature of the book, it promotes last-minute preparation and therefore, it can be said that preparation from RS Aggarwal’s book is more time-efficient.
- The level of questions that are available for practice in this book corresponds to the syllabus issued by the CBSE for Class 6. The solutions are primarily based upon the NCERT textbook that is emphasized the most by the CBSE. So, practising questions from RS Aggarwal’s book will be a very constructive effort to score good marks in the exams.
- Students can easily find quality questions to solve and practice accordingly. Instead of the bulk of problems, RS Aggarwal consists of important portions of each concept with detailed examples to understand the topics without any confusion. Therefore, students are less likely to feel overburdened or stressed out while solving questions from RS Aggarwal.Â Â

There are several demerits of using RS Aggarwal’s book for reference during the preparation for Class 6 exams. These include:

- Even though there are many important questions, RS Aggarwal’s book lacks different objective types as well as multiple-choice type questions. It is usually seen that such questions are more tricky and will require thorough basic knowledge about the topics. There is a high chance that students who prepare from RS Aggarwal may skip some crucial topics that can harm their performance in the examinations.Â
- Students who prepare from RS Aggarwal’s solutions try to memorize the approach to follow while solving the questions. Mathematics is concerned with more and more practice. Therefore, it is advisable that the students must refrain from memorizing the shortcuts and tricks to solve questions mentioned in RS Aggarwal. Instead, students must focus on developing a strong and clear understanding of the formulas that have to be used to solve the questions.

It is essential to note that NCERT textbooks are sufficient to establish a clear understanding of the basics. But, other reference books such as the ones mentioned above will inculcate the idea of consistency and hard work within the students. If the students develop a habit of practising mathematics regularly, a keen interest will gradually emerge for the subject. Such interest will be very beneficial as students get promoted to successive classes. A student’s perseverance and willingness to continue learning mathematics will automatically determine the performance in the exams.
