This is a big mistake, as 80% of aspirants sometimes fail Prelims because of the qualifying CSAT paper. While the syllabus of this paper is relatively easy, aspirants should not underestimate it and prepare diligently. 

Neglecting Practice 

Skipping mock tests and ias previous year question paper is a common pitfall. Without sufficient practice within the given time period, aspirants fail to develop exam temperament and time management skills. 

Poor Time Management in The Exam 

Spending too much time on a few difficult questions can leave many other questions unanswered. Also, aspirants should not spend too little time on practicing easy questions because it is easy to lose perspective and take subjects for granted. A balanced approach and the ability to move on if stuck are essential along with the ability to understand which topics require how much time. 

Treating CSAT As A Basic Exam 

Aspirants often treat CSAT as a standard mathematics or English test, focusing on school level effort rather than developing the ability to think sharply and analyze complex questions that test perception and problem-solving skills. Treating CSAT as a basic exam is a very big mistake. 

Not Working on Foundational Concepts 

Due to mental barriers or overconfidence, some aspirants neglect the basics of quantitative aptitude, logical reasoning and comprehension. Strong foundations are crucial for tackling higher level questions. Not working on foundational concepts can lead to potential failure. 

Failing To Analyze Mistakes 

Taking mock tests without reviewing both correct and incorrect answers and identifying weak areas makes practice ineffective because the entire objective of mock tests is to help aspirants understand their mistakes. Introspection and analysing mistakes is very important. 

Guessing Answers 

Attempting questions purely on guesswork is risky due to negative marking. Learning and applying elimination techniques can reduce chances of negative marking but this requires practice. Elimination techniques such as identifying opposite options and removing unfamiliar options can help. 

Lack of Structured Study Plan 

Approaching CSAT preparation haphazardly without a concrete study plan for covering all topics evenly can lead to an uneven coverage of the syllabus. When aspirants lack a structured plan, the preparation doesn’t reap fruitful results. 

Not Reading The Question Properly 

In a rush to save time, aspirants may only read keywords of a question and assume the rest, which often leads to answering the wrong question or missing crucial details. Aspirants should read the questions properly to understand what is expected from them during the exam. 

Relying on Single Sources 

Depending solely on one book or coaching material for all sections of the CSAT can limit understanding. A holistic approach, using standard books and quality online resources, is recommended for success in the Prelims.
