Students study hard and try to do their best to score more than 80% in the Science Board Examination. They have to focus on this subject as it will decide whether a student will be able to opt for the Science stream in Class 11^th or not. 

Before knowing the tips directly, students should be aware of their syllabus. If they don’t know what is coming in their exam then they will not be able to start with their preparation. The list of chapters based on the CBSE curriculum for Class 10^thScience is given below:

• 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 –Light – Reflection And Refraction
• Chapter 11–The Human Eye And The Colourful World
• Chapter 12 – Electricity
• Chapter 13–Magnetic Effects Of Electric Current
• Chapter 14–Sources Of Energy
• Chapter 15–Our Environment
• Chapter 16 –Sustainable Management Of Natural Resources 

According to the CBSE guidelines, students have to study these chapters from the NCERT book. Now let us go through the exam pattern. This will assist you in preparing for your Class 10 Science Board Examination. 

Underneath is the blueprint or the exam pattern which is necessary to understand by each student during their preparation.

The theory paper will be split up into 4 sections:

• Part A –20 questions of 1 mark each. Total marks will be 20 marks.
• Part B –Each question will be of 2 marks. There will be 6 questions. Hence, the total marks of this section will be 12 marks.
• Part C –7 questions (3 marks each) (Total marks – 21 marks)
• Part D – This section carries 15 marks. The number of questions is 3 which are of 5 marks each.

The Science Board Examination of Class 10 is of 100 marks. The marks distribution is discussed here:

• In the internal assessment, students are allotted 20 marks. These 20 marks are based on the written exams conducted by the school and the practical exam.
• 80 marks are allotted to the students in the theory exam. The weightage of the units is:

1. Chemical Substance – Nature and Behaviour (25 marks)
2. World Of Living (23 marks)
3. Natural Phenomena (12 marks)
4. Effects Of Current (13 marks)
5. Natural Resources (7 marks)

Students start their preparation 3 months before the examination. To qualify for this exam, students have to put in all the effort. 

Some of the preparation tips are provided to students in this article. Hope this will help them in scoring 80% and more in the Class 10 Science Examination.

• Subject-Wise Preparation Tips.

The Science Examination theory paper is divided into three sub-subjects. These are Physics, Chemistry and Biology. The preparation tips for these subjects are given below:

1. For Chemistry
   1. As this section contains lots of formulas, chemical compound names and equations, prepare separate registers for them so that you can use them at the time of revision.
2. For Physics
   1. Learn all the theorems and formulas by heart. Practice each numerical to have a grasp on the topics.
   2. Diagrams are very scoring in exams. You can represent your answers in the form of flow charts and diagrams, so practice them thoroughly.
3. For Biology
   1. Memorize all the processes, flow charts and names of scientists. Also, learn to make neat, clean and labelled diagrams.

• Other Educational Materials.

Refer to guide books or any other reference books to comprehend the chapters in a better way. These books will provide you with short notes for all the chapters. You will find all the NCERT Solutions and extra questions in this book. Make use of these extra questions to strengthen your concepts.
