1Copy the figures
The subject is asked to draw the shown geometrical figures (printed on the board) onto a provided ruled paper, without altering the size
(The original figures cross three units on the same paper)
Symmetrical figure…0 
else…1
Number of units crossed 


3-… 

2Group similar objects
The subject is shown one card (of a set of cards) showing the pictures of a few things belonging to two different categories (birds and vegetables, say). The subject is asked to place the blocks of the same color on objects of the same type
Number of objects misgrouped …/2

3Trace the sequence
The subject is shown a card to trace a well known sequence (like seed-sapling-tree-wood log-table)
The examiner waits for a maximum of 1 minute, else proceeds to the next step
Score the time in seconds
0–10 s…0, 11–20 s…1, 21–30 s…2, 31–40 s…3, >40 s…4

Name the animals
A: the subject is shown an animal (a cow, say) and is asked to name it
Score time in seconds
<5 s…0, 5–15 s…1, >15 s…2
B: the subject is asked to separate animals of a certain kind from among the toys<15 s…0, else 1

Build the wall
The subject is asked to build a two layered wall on the given line using the provided blocks The examiner waits for a maximum of 1 minute and then proceeds to the next step
A well built wall…0
Asymmetrical…1
Unable to build…2
(Asymmetry is defined as inability to place the blocks linearly either along the line in the game board or inability to stack two layers one over the other)
Instruction box
The subject is made to hear three different bell sounds like the alarm, ambulance, and church bell using the audio device. He is also asked to be vigilant about the things he sees in the rest of the game

Immediately following this, the subject is asked to recall the arrangement
Number of objects recalled correctly(6-…)/2

8Cut along the line
The subject is asked to cut along a line with both indentation and curve
The graph sheet on the reverse is analyzed for deviation
