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.
Board examinations can become the stuff of nightmares for many young minds. It is important to create a relaxed environment for them to prepare in earnest for the tests.
Questions about scoring good marks in each paper, the subconscious fear of the board exams, and most importantly, perhaps, why board exams exist, in the first place, go through the minds of each student!. The important thing to remember is this - it is just a round of examinations that will set you on your chosen academic path.
Obtaining good scores in the Board exams reflects the amount of hard work, dedication, and sincerity that a student has put into it. So, how does one prepare for Class 10 board exams, especially for traditionally challenging subjects such as Chemistry?

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 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.
They come in an easy language, accompanied by illustrations and images that make them attractive as well as interesting for students to use and retain easily.
The revision notes are prepared by subject matter experts (often high school Chemistry teachers and Chemistry professors). Thus, the notes are designed to provide students with an advantage, come exam day!
When should you prepare revision notes?
There is a time for everything in life, including the preparation of revision notes for your Chemistry chapters. Here are some useful tips to keep in mind:
- 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! Moreover, the examiner knows immediately about the clarity of thought that has gone into the exercise.
Sample Papers and Past Question Papers
A month or a couple of weeks prior to your Chemistry exam, sit down with sample papers and past question papers that are released by the exam boards for the benefit of students. Along with the past years' question papers, detailed solutions are also provided by experts in Chemistry.
The express purpose of sample papers past question papers is to give students an idea of the format that will be followed in the actual exam paper.
Prior knowledge of the structure of the question paper helps in preparing an adequate and effective learning plan for Chemistry. Students are able to identify areas of weakness and strength in their understanding of the concepts of Chemistry. Also, these mock tests are a great self-assessment tool. Remember the old adage - practice makes one perfect!
Take chemistry crash course here.
Use the Available Reference Books
Finally, going by the pattern of board exams in India, questions are usually based on a few recurring themes. Look out for subtle changes in the language used and cull out these themes as you practice with the help of sample and past question papers.
Class 10 students will do well to adhere to the NCERT textbook. Try to solve all the NCERT questions and examples. Use the NCERT Exemplar Problems as a mock question paper as board exam questions are often based on them, sometimes even completely unchanged in their language and tone. You can also use some of the most celebrated reference books such as Lakhmir Singh Chemistry Class 10 (CBSE) and Selina Concise Chemistry Class 10 (ICSE).
The first major step is to push yourself to start revising. Devise a comprehensive revision strategy and follow it thoroughly. Make daily or weekly schedules, according to your learning style. The more you revise and practice, the better chance you give yourself at excelling in your exam.
