Navodaya Mental Ability Test: Question Types and How to Solve Them
The JNVST Mental Ability Test has 40 picture-based questions worth 50 of the 100 marks, to be answered in 60 minutes. Every question belongs to one of about ten figure types, and each type has a simple, repeatable method. Learning those methods one at a time is the fastest way to improve.
Why does this section matter so much?
Mental ability carries half the marks and is not taught at school, so it is where most marks are won or lost. The good news: the question types repeat every year, and children improve quickly with short daily practice.
The question types and a method for each
Odd man out
Four figures share a rule and one breaks it. Compare the figures one feature at a time: number of sides, shading, direction, number of parts.
Figure match
Find the figure identical to the given one. Pick one small detail of the question figure and check it in each option to eliminate quickly.
Pattern completion
A part of a pattern is missing. Look at the lines and shapes around the gap and continue them; the right piece joins without any break.
Figure series
Figures change step by step. Track one element at a time: does it rotate, move, grow or gain a line? Apply the same change once more.
Analogy
“A is to B as C is to ?” Name the change from A to B in words (for example, “turns upside down and becomes shaded”), then apply exactly that change to C.
Geometrical figure completion
Choose the pieces that complete a shape, often a square. Check that the sizes and angles of the pieces fit the gap.
Mirror imaging
In a mirror, left and right swap but top and bottom stay. Check the side closest to the mirror first.
Punched-hole patterns
A folded paper is punched, then opened. Unfold one step at a time, copying each hole across every fold line.
Space visualisation
Picture how pieces fit together or how a figure looks from another side. Count corners and edges to rule out impossible options.
Embedded figures
Find the option in which a simple figure is hidden. Trace the simple figure’s outline with a finger inside each option.
A 6-week practice plan
- Weeks 1–2: learn two question types a week; 15 questions of each type a day.
- Weeks 3–4: learn the remaining types; mix in yesterday’s types for revision.
- Week 5: mixed sets of 20 questions in 30 minutes.
- Week 6: full 40-question sections in 60 minutes, reviewing every mistake.
Exam-day tips
- You have about 90 seconds per question; skip a hard one and come back to it.
- Look at all four options before choosing; two often look almost the same.
- Mark the OMR bubble carefully and check the question number each time.
