Basic idea of the domestic electric circuit. Also, remember the working of fuses (low melting point) and earthing.
Remember to follow every single free job alert religiously.
Part III: Chemistry Essentials Factual Recall and applications
– Chemistry questions in the Pearson Group D exam are more factual, definition-based and of common application type than numerical.
Chemical Reactants and Reactors: It is the chapter you have to clear for the basics. Learn to identify the different types of reactions – combination, decomposition, displacement, double displacement, redox. Key Focus – corrosion rusting of iron and rancidity oxidation of fats/oils causes and prevention. Can you balance simple chemical equations? Identify the oxidizing and reducing agents.
Acids, Bases, and Salts: This is a powerhouse of direct questions. Focus on the definitions, the pH scale, and the uses of common compounds. Key Focus: Memorize the pH values for common substances: blood is slightly basic; the stomach is strongly acidic. Also memorize the preparation and uses of key compounds like, Bleaching Powder, baking soda, Washing soda, and Plaster of Paris.
Metals and Non-Metals: The key here is understanding the differences in physical and chemical properties. Know which metals are highly reactive and which are non-reactive. Key Focus: Study the concept of the Reactivity Series and its application in displacement reactions. Understand the basic concepts of ionic and covalent bonding.
Carbon and its Compounds: While detailed organic chemistry is outside the scope, you must know the basics of the versatile nature of carbon, its tetravalency and the difference between saturated and unsaturated hydrocarbons.

Part V: The Strategy for 25/25
a. Your commitment to NCERT’s will put your miles ahead, but scoring a raw 25 means mastering the execution of five critical strategies
: i. Dual Reading Cycle: Read every Physics and Chemistry chapters twice, once for understanding and comprehensive knowledge and the second loop for recognition of specific facts, and formulas.
ii. Formula Sheet: This requirement involves a specific and single sheet dedicated to listing all formulas, facts, and appropriate units from Physics and Chemistry. For every ten minutes, spend 10 minutes during your newspaper reading or general awareness time, going over this one page once.
iii. The Time-Bank: In the examination hall, the GS section should be solved in less than 10 minutes. Every fact in GS is either known or completely unknown, allowing you to use this section to earn a time-bank which can then be spent on lengthy calculations in Math and Reasoning sections?
iv. No Guessing: Do not to work on guessing in the GS section. The negative marking for GS’s wrong answer costs you your half an hour easily earned in Math and Reasoning. Move on if the annotated fact does not return to your mind. Your RRB Group D exam victory depends mostly on acing the General Science section. By focusing on achieving mastery over NCERT Class 9/10 Science details, you get 25 victory laps while the competition is pushed behind. Focus, memorize, win these 25 marks.
