Short answer: Pick one reasoning or puzzle book, solve a few sets a week without a timer first, then add timing. Review every wrong answer before moving on.
Why reasoning needs its own practice
Logical reasoning sets in CAT are about arranging information, such as seating, scheduling, grouping and conditions, and then answering several questions from one setup. Reading more does not train this. Solving sets does.
Choose one book and stay with it
One book with graded sets is enough for most learners. Look for a book that explains the method behind each type of set and gives full solutions. Buying several books of the same level mostly gives you repeated question types. A second hand copy is fine if the pages are not already filled in; see how to check book condition before buying.
A simple weekly routine
- Solve two or three sets slowly, without a timer, and draw tables or diagrams
- Mark the sets you could not finish and write down the step where you got stuck
- Redo those sets a few days later
- Once you finish most sets correctly, begin timing each set
Learn to skip
Some sets are built to take a lot of time. Part of preparation is recognising when a setup is too tangled and moving on. Practise this by deciding within the first couple of minutes whether to continue.
Keep an error log
Write down each type of mistake: misread condition, missed case, or wrong diagram. After two weeks you will see patterns. The method in our post on making an error log works well for this. For more CAT book ideas, see the CAT and MBA entrance guides.
How long to keep at it
Reasoning skill builds slowly, so short regular sessions beat occasional long ones. Thirty to forty-five minutes on most days, with a longer session once a week for a mixed set, is a sensible pattern for many learners. Adjust this to your own timetable and the time you have before the exam.
Also notice which set types you enjoy and which you avoid. Avoided types are usually the ones where practice pays most, because easy sets are already comfortable. Give those types a fixed slot each week so they do not get dropped.
Frequently asked questions
Do I need a separate book for logical reasoning?
A dedicated book helps because it gives graded sets and full solutions. One good book is enough.
When should I start timing my practice?
Start timing once you can complete most sets correctly without a timer. Early on, accuracy and method matter more than speed.
Can I use a second hand reasoning book?
Yes, if the sets are not already solved in pencil or pen and the pages are complete.
