What is logical reasoning?

Logical reasoning is thinking step by step to reach an answer you can be sure of: spotting the pattern in a series, finding the odd one out, cracking a code, working out who sits where, or deciding whether a conclusion really follows. It is the reasoning section of Olympiads (such as the mental ability part of maths and science Olympiads), school aptitude tests and scholarship exams, and the same IQ-style thinking that helps in maths, science and everyday decisions. This free course is useful from Class 3 to Class 10: Part 1 (ages 8–11) builds pattern skills, Part 2 (ages 10–13) covers order and arrangement, and Part 3 (ages 12–16) moves on to syllogisms, truth-and-lie puzzles, logic grids and data. Every lesson explains the method, works an example, and gives unlimited practice with “Show me how”, a 20-question test, a badge and printable worksheets.

Logical reasoning kaise sikhe? (Hindi)

हर दिन एक टाइप का सवाल लें — जैसे संख्या श्रृंखला, कोडिंग–डिकोडिंग या दिशा ज्ञान। पहले तरीका समझें, फिर उदाहरण देखें और 10–15 सवाल खुद हल करें। अटकें तो “Show me how” दबाएँ। रोज़ थोड़ा अभ्यास करने से रीजनिंग तेज़ होती है।

The questions here are our own, made fresh by the computer each time.

How can my child get better at reasoning questions?

Practise a little every day, one type at a time. Always draw the question — a row of boxes, a compass, a family tree or a clock — and check the answer against every clue. Speed comes after accuracy.

What are the most common reasoning question types?
