Preparing for the Common Admission Test (CAT) is as much about mastering concepts as it is about minimizing errors. While we often focus on difficult questions and tricky topics, a surprising number of marks are lost due to avoidable, silly mistakes. These often happen not in the toughest questions, but in areas where we feel the most confident. Here are three question types that commonly lead to careless mistakes — and how you can avoid them.
Before diving in, make sure you’re familiar with the CAT exam date, CAT application form, CAT exam syllabus, and CAT exam pattern. Being well-informed about these basics can help you align your preparation better and avoid last-minute confusion.
1. arithmetic questions with multiple steps
Why they cause mistakes:
These questions often seem easy at first glance. But they involve several steps — percentages, ratios, averages, or simple interest calculations. A minor calculation slip or overlooking a unit conversion can lead to the wrong answer.
Common errors:
- Missing one of the steps
- Copying the wrong number from the question
- Misreading the data or question requirement
Fix:
- Use rough sheets methodically. Write down each step.
- Always re-read the question before marking your answer.
- Cross-check units and calculations.
- Practice similar problems under timed conditions to build muscle memory.
- Regularly revise related concepts from the CAT exam syllabus to stay sharp.
2. reading comprehension (RC) inference-based questions
Why they cause mistakes:
Inference-based questions in RC sections test not what is directly stated but what can be logically concluded. Students often overthink or make assumptions not supported by the passage.
Common errors:
- Choosing an option that “sounds right” but isn’t supported by the passage
- Rushing through the passage
- Letting personal bias interfere with interpretation
Fix:
- Stick to what the passage says. If it isn’t mentioned, don’t assume it.
- Underline keywords while reading to stay focused.
- Read the question carefully and eliminate options using the process of elimination.
3. logical reasoning puzzles with constraints
Why they cause mistakes:
Logical reasoning sets, especially those with multiple constraints (like seating arrangements or scheduling), require precision and a clear strategy. One wrong assumption can derail the entire solution.
Common errors:
- Misinterpreting a constraint
- Forgetting a previously derived condition
- Mixing up elements or variables
Fix:
- Create a clean, labeled diagram before attempting the question.
- List all constraints clearly before jumping into solving.
- Keep track of assumptions and verify them against all conditions.
- Don’t rush. Accuracy matters more than speed in these sets.
Final thoughts
Silly mistakes are the most frustrating kind because we know we could have avoided them. Identifying the types of questions where you’re most prone to error is the first step toward improving your score. Combine awareness with structured practice and a checklist-based approach to minimize these errors in the CAT exam.
The key to cracking CAT isn’t just about knowing more — it’s about avoiding preventable losses. Stay updated with the CAT exam date, fill out the CAT application form on time, follow the CAT exam syllabus strictly, and practice according to the CAT exam pattern for the best results.
