CAT Study Plan

One-Book vs. Multi-Book Strategy: What Works Best for CAT Preparation?
CAT aspirants often struggle between sticking to one trusted book or exploring multiple sources. Both methods have distinct benefits and drawbacks. The right choice depends on preparation stage, strengths, and time left. A balanced approach maximises concept clarity while ensuring exposure to diverse problem-solving patterns.
Begin with One Reliable Core Book Per Section
Choose one standard book for each section—Quant, VARC, and DILR. This avoids early confusion and builds strong basics. For example, Arun Sharma’s How to Prepare for Quantitative Aptitude is enough to understand concepts before diversifying.
Sticking to one source initially ensures you don’t waste time comparing approaches when your fundamentals are still weak.

Balance Between Speed and Accuracy Using Multi-Source Practice
One book might help you understand methods, but another might train you on shortcuts or faster approaches.
Multi-book exposure helps you experiment with alternative solving techniques and select the most efficient for the exam hall.
Leverage Previous Year Papers as a Reality Check
After completing a book, test yourself with actual CAT papers. If you still find unfamiliar problem types, that’s the signal to diversify into another source.
Past papers also help you filter out irrelevant practice from books that go beyond CAT’s difficulty level.
Integrate Sectional Tests Alongside Books
Books build knowledge, but only timed tests build exam temperament.
Combine one-book study with sectional tests to measure application under pressure. If your accuracy drops despite knowing concepts, additional sources may provide alternative explanations or better practice patterns.
Can You Do CAT Self Study with Books?
Yes, you can do CAT self-study with books, provided you choose the right resources and build a disciplined plan. Books alone won’t guarantee success unless you approach them strategically—focusing on concepts, practice, timed tests, and analysis. The key is not the number of books but how effectively you use them to bridge gaps and simulate exam conditions.
Avoid multiple books; it creates confusion. For QA, use Arun Sharma or Nishit Sinha. For VARC, Norman Lewis + RC practice books. For DILR, Arun Sharma DILR. Stick to one trusted source.
First clear basics from books, then directly attempt sectional tests to apply. Reading passively is useless.
Solve CAT-level or higher difficulty questions. Avoid outdated or too-easy exercises.
Books can’t replicate adaptive exam stress. Take mocks after 2–3 months of book study, and link weak areas back to book chapters.
Revisit only those chapters where mock errors repeat. This ensures targeted book usage instead of random reading.
Supplement with previous year CAT papers, AIMCATs, and online practice sets.

On the first day, 3 groups of customers came in and ordered at 6.00 pm, 6.10 pm, and 6.13 pm. The first order was for a plate of Egg Tortillas, two plates of French Toast, and three plates of Egg Bhurji with French Fries.

On the first day, 3 groups of customers came in and ordered at 6.00 pm, 6.10 pm, and 6.13 pm. The first order was for a plate of Egg Tortillas, two plates of French Toast, and three plates of Egg Bhurji with French Fries.

Two friends Moloy and Niloy passed out from the Purulia Institute of Science and Technology with B.Tech degrees in Mechanical Engineering, but even after a year placement was hard to find. So they decided to take the challenge head-on, came down to Kolkata, rented a garage space on Park Street, and having an affinity towards making people enjoy good food, started their firm named 'B.Tech Bread-Omlette Wala'.
They started with three items on the menu. One was the French Toast which could be prepared in 3 minutes. The second was the Egg Tortillas which took 15 minutes to prepare. Any one of Moloy and Niloy could prepare any one of them at a time. The third was the Egg Bhurji with French Fries. This however was prepared on an automated fryer which could prepare 3 servings at a time and took 5 minutes irrespective of the number of servings equal to or below 3. The fryer did not need anyone to attend to it, and the time to put in the raw ingredients could be neglected. So one could tend to the preparation of other items while the Egg Bhurji with French Fries were being prepared.
