General Science

The marks distribution for Class 10 General Science can vary depending on the education board (CBSE, ICSE, or state boards). Here's a general idea based on common patterns, particularly for CBSE:Theory Paper:Total Marks: 80The theory portion is typically divided into Physics, Chemistry, and Biology. Each section has an almost equal weightage, but specific chapters might carry more importance based on the syllabus.Physics: Topics like Electricity, Light, and Energy Conservation.Chemistry: Chemical Reactions, Acids and Bases, and Periodic Table.Biology: Life Processes, Heredity, and Environment.Internal Assessment:Total Marks: 20Comprises practicals, assignments, periodic tests, and lab activities.Boards like ICSE and state boards may have slightly different patterns, so it's best to check the syllabus provided by your board for precise details. Regular study and focusing on high-weightage topics can help maximize your score!

In the NDA (National Defence Academy) written exam, the General Science section is part of the overall paper, which includes subjects like Physics, Chemistry, and Biology. The weightage of General Science is divided as follows:Physics: Typically, questions from Physics hold the largest weightage in the General Science section, covering topics such as mechanics, optics, electricity, and magnetism.Chemistry: Questions from Chemistry include topics such as physical chemistry, inorganic chemistry, and organic chemistry, usually making up a smaller portion compared to Physics.Biology: While Biology has a comparatively lower weightage, it still plays an important role in the overall score. The questions generally cover topics related to human anatomy, plant biology, and basic environmental science.In total, the General Science section carries approximately 30-40 marks of the total 900 marks in the NDA written exam, but the exact weightage can vary slightly depending on the year. 

For Basic Science and Engineering, candidates can refer to the NCERT Science Books (Class 10 to 12) and be well-versed with all the basic concepts. They must also refer to the Basic Science and Engineering for Indian Railways (RRB) Assistant Loco Pilot Exam Stage II.Physics include topics such as work & Motion, Lens, Work energy, Electricity, etc. Chemistry will include Basic Reactions, chemistry in everyday life, periodic tables, Acid Bases & Salt. Biology will comprise both plant & human analogy.Chemistry: Chemical Reactions and Equations, Acids, Bases and Salts, Metals and Non-Metals, Carbon and Its Components, Periodic Classification of Elements, etc. Life Science: Life Processes, Control and Coordination, How do Organisms Reproduce, Heredity and Evolution, etc
