Chemistry concerns itself with the utilization of natural substances and the creation of artificial ones. Cooking, fermentation, glass making, and metallurgy are all chemical processes. Some drastic advancements took place in the field of Chemistry at the turn of the 20th century. Chemists, professional researchers in Chemistry and Chemistry professors started unraveling the mysteries behind the complex chemistry of living organisms, and a molecular interpretation of health and disease.
How to Make the Best Use of Reading Materials like S.Chand Chemistry Class 10
The major boards of education in India - Central Board of Secondary Education (CBSE) or Indian Certificate of Secondary Education (ICSE) combine the curricula for Physics, Chemistry and Biology into one subject of study, viz. Science.
Preparation Tips for Class 10 Chemistry Exam
To start with, pay attention in Chemistry class! Thoroughly study the NCERT Class 10 Science textbook as question papers are based on this book.
Improve your speed of writing and accuracy of answers through extensive practice of sample papers and in-depth preparation of the subject.
There are many 10th class chemistry study materials available that help in the preparation for the final exams, such as S.Chand Class 10 Chemistry, Lakhmir Singh Chemistry Class 10 Solutions, prepared by the very experienced teachers of science - Lakhmir Singh and Manjit Kaur.
Know the Exam Pattern and Marking Scheme
The question paper for CBSE Class 10 consists of 80 marks, divided into 5 sections. The distribution of marks and the number of questions for each section is as follows:
|Sections Name||Marks per Question||Total Questions||No. of words for Answering|
|A||1||2||1 word or 1 sentence each|
|B||2||3||30 words each|
|C||3||10||50 words each|
|D||5||6||70 words each|
|E||2||6||Brief answer (Word limit not specified)|
The above data has been collated from analyses of previous years' question papers. It is only suggestive in nature. Students should bear in mind that there may be slight variations in the upcoming exam pattern.
Revise the Syllabus More than Once
Constant revisions of lessons help students to chalk out learning strategies for topics that they are strong in and those that need improvement. Keep the NCERT textbook questions handy as you go through the revisions.
Revising with Past Papers and References like S. Chand Chemistry Class 10
Revising by solving past question papers of Chemistry allows students to check the progress of their revision and to highlight those areas that need further improvement.
Past papers give you an idea about the structure of the question paper.
Your Chemistry coursework, as taught in class, along with Chemistry class 10 notes come together to make previous years' question papers a great ally as you prepare for the first major competitive exam of your life.
Familiarity with Questions
Solving past exam papers of Chemistry helps students become familiar with the types of questions that examiners set in exams. Continuous practice with these papers also allows them to pick up on subtle changes in the language of the questions.
Variety of Topics
Revising with the help of past exam papers often force students (for the better) to extend their coverage of topics to even those they don't like very much. Organic chemistry, anyone?
Reduce the Learning Gap
With past question papers, students are able to identify learning gaps faster, work on bridging those gaps and, in time, develop a degree of self-confidence about having dealt with those learning gaps.
Reduce Exam Stress
The most far-reaching and long-lasting advantage of using previous years' Chemistry question papers is that they help you reduce anxiety vis-a-vis the impending examinations. In other words, when done properly, they help you take the fear out of exams.
Make Optimum Use of Learning Resources Like S.Chand Chemistry Class 10
The Board exams for Class 10 is the first major academic test that students have to compete at a national level, be it CBSE, ICSE or any other state board of education. Not surprisingly it is a time when students often find themselves in quandary as to how to prepare best for the impending exams.
Class 10 Chemistry Revision Notes
There are various online learning platforms that offer curated revision notes, in adherence to the various syllabi prescribed by different boards of education in the country. The revision notes packages also include additional details about a particular topic that students find especially helpful while preparing for their Chemistry paper.
Why do you need the revision notes?
Class 10 revision notes are a useful resource for revision containing, on many occasions useful learning tools such as mind maps, formulae, definitions, diagrams, and concise explanations of theories and concepts of Chemistry. Often, these notes are color-coded according to the topic they are designed for.
When should you prepare revision notes?
There is a time for everything in life, including the preparation of revision notes for your Chemistry chapters.
- Write down your notes immediately after you finish a chapter. This way, you can capture the key points of the topic you just revised and retain them.
- Maintain and update your revision notes weekly. This will help you check the power of your memory.
- A quick round of notes on the eve of the exam. This allows you to recap the key takeaways from a chapter, without having to invest a lot of time in it.

Take a quick look at the important reactions
Chemical reactions, along with their chemical equations are a critical part of the study material for Class 10 Chemistry. If you get your chemical reactions right (by that, we mean balanced reactions, accurately explained), you score really high with them!
Score High with Exam Prep Resources like S. Chand Chemistry Class 10
It is essential that students familiarize themselves with the entire Class 10 syllabus of Chemistry, irrespective of the Board of education they are affiliated to. This step should come before any of the other exam prep tricks such as solving past papers, etc.
Class 10 Chemistry Syllabus
Familiarity with the curriculum helps in the understanding of the unit-wise distribution of marks, important topics that need extra preparation, components for internal assessments, along with the actual design of the question papers in the final exam.
