One needs to focus on all concepts while preparing for Class 10 Science. With some really good study material and complete focus, you can perform very well in your exam.

Here are few tips to guide you in the right direction with the preparation:

1. Make a proper Time-table and start with basics:

The first step in your preparation should be to build a strategy and make schedule and follow it strictly. Give good amount of time to all subjects so that you do not miss out on any topic. Your time is precious, use it judiciously. Make sure to strengthen your basics initially by studying from the NCERT Textbooks. Study additional books only after you know that your basic concepts are clear

NCERT Textbooks and Solutions-

Chapter 1 - Chemical Reactions and Equations

Chapter 2 - Acids, Bases and Salts

Chapter 3 - Metals and Non-metals

Chapter 4 - Carbon and its compounds

Chapter 5 - Periodic Classification of Elements

Chapter 6 - Life Processes

Chapter 7 - Control and Coordination

Chapter 8 - How do Organisms Reproduce?

Chapter 9 - Heredity and Evolution

Chapter 10 - Ray Optics - Light : Reflection and Refraction

Chapter 11 - Ray Optics - The Human Eye and Colorful World

Chapter 12 - Electricity

Chapter 13 - Magnetic Effects of Current

Chapter 14 - Sources of Energy

Chapter 15 - Our Environment

Chapter 16 - Management of Natural Resources

2. Learn formulae and Important topics:

All the formula included in the Class 10 science syllabus should be on your tips so that during the exam , you don't have to waste any time remembering them. The exam contains direct formulae and theorem-based questions. Hence, revise them thoroughly to solve questions accurately. Also, do study the important topics mentioned with utmost concentration. After you study a chapter, make a habit of noting down some important points and formulae. This will help in remembering the concepts.

3. Solve Previous Years Papers:

Practice is really important as you will be able to retain various topics in your mind for a long time. Previous Year question papers are a must to solve as they will help you understand the pattern of the exam. Also, you will be able to know your strengths and weaknesses. Time yourself while you attempt them in examination hall conditions. After trying every paper, evaluate yourself.  This practice will help you gain self-confidence, which is one of the most important things to have during the exams.
