Online Practice of Mechanical Tests

Welcome to the page of Mechanical Tests which are basically used to measure Mechanical Aptitude of the students.

Mechanical Aptitude tests are very helpful for the preparation of Officers tests in Army, Navy and PAF, particularly in ISSB.

These tests are also helpful for different commissioning tests in Pak Army and in Pak Navy which have been designed to develop mechanical skills through the given mechanical testing.

Moreover, mechanical aptitude practice tests increase your Intelligence Tests, Academic Tests & Interview questions with the whole procedure. For the preparation of all tests, Click Here and for notes Click Here. Further detail may be taken at any time. Contact us for more detail.

Purpose of Mechanical Tests in Initial Tests of Forces

Mechanical Tests are also useful in ISSB initial tests which basically define about attitude towards certain trends that you have. If you will show good aptitude in mechanical tests then you will be alloted best field in the future.
