This video, "CSAT Coding Decoding Made Easy," is a comprehensive revision session for the UPSC CSAT 2026 exam, focusing on Coding-Decoding. The instructor explains various types of coding-decoding questions, concepts, short tricks, elimination techniques, and a time-saving approach for the exam. The video also includes discussions of Previous Year Questions (PYQs).



Introduction to Coding-Decoding and PYQ Trend (0:45-1:16): The video begins by stating that it will cover coding-decoding questions from 2014 to 2025, starting from older questions to understand the trend.
Word-to-Word Coding (Rearrangement) (1:38-4:37): The first example shows how words like "SYSTEM" and "NEARER" are coded by rearranging their letters. The same logic is then applied to "FRACTION" to find its coded form.
Number-to-Word Coding (Common Code Identification) (4:41-8:10): This section demonstrates how to find the numerical code for a specific word by identifying common numbers and words across multiple given statements. For example, "256 means Red Color Chalk," "589 means Green Color Flower," and "254 means White Color Chalk" are used to determine the code for "White."
Letter-to-Number Coding (Direct Substitution) (8:32-11:47): The video explains how specific letters are directly substituted with numbers in words like "RAMAN" and "DINESH." This pattern is then used to decode "HAMAM" and later "FRANCE" and "GERMANY" to decode "YEMEN."
Letter-to-Letter Coding (Positional Shift - Addition/Subtraction) (11:58-17:01): This part covers coding where each letter in a word is shifted by a certain number of positions (e.g., +1, -1, +2, -2). The example of "MUMBAI" being coded as "LSJXVX" is used to explain this concept, and then applied to "DELHI." The instructor emphasizes remembering the alphabetical order and positions.
Alphabet Pattern Recognition (Case Change and Alternating Cases) (17:07-19:30): An interesting example is presented where every alternate letter from 'B' onwards is written in lowercase, and the rest are capitalized. The task is to find how the first month of the second half of the year (July) would be written.
Letter-to-Number Coding (Multiplication of Positional Values) (20:11-22:34): This section demonstrates how numerical codes are derived by multiplying the positional values of letters. Examples include "GHI" to "15778" and "DEF" to "912." The same logic is then applied to "ABC."
Letter-to-Letter Coding (Sequential Positional Shift) (22:38-25:47): The video explains a pattern where the shift in letter positions increases sequentially (e.g., +1, +2, +3, +4). This is illustrated with "ACPQ" becoming "BESU" and applied to "MNGI."
Letter-to-Letter Coding (Alternating Addition/Subtraction) (25:50-28:22): This part covers a pattern where letters are alternately shifted by -1 and +1. The example of "MATHEMATICS"
