Unit III – Aptitude Test 20 marks

Numerical And Figurework Tests: (4 Marks)
These tests are reflections of fluency with numbers and calculations. It shows how easily a person can think with numbers. The subject will be given a series of numbers His/Her task is to see how the numbers go together to form a relationship with each other. He/She has to choose a number which would go next in the series.o Verbal Analysis And

Vocabulary Tests: (6 Marks)
These tests measure the degree of comfort and fluency with the English language.These tests will measure how a person will reason with words. The subject will be given questions with alternative answers, that will reflect his/her command of the rule and use of English language.
o Visual And Spatial/3-D

Ability Tests: (4 Marks) These tests are used to measure perceptual speed and acuity. The subject will be shown pictures where he/she is asked to identify the odd one out; or which comes next in the sequence or explores how easily he/she can see and turn around objects in space.o Abstract Reasoning Tests: (6 Marks)This test measures the ability to analyse information and solve problems on a complex, thought based level. It measures a person’s ability to quickly identify patterns, logical rules and trends in new data, integrate this information, and apply it
to solve problems.
