## How do the Civil Engineering Board Exam Problems are structured?

The Civil Engineering Board Exam Problems and their implementation are presented here.

Ever since the promulgation of the Resolution No. 02 Series of 1995 by the Philippine Board of Civil Engineering as provided by the Civil Engineering Law in the year 1995 the computerized test was implemented. This is unprecedented because comparably those past board examinations are administered manually. Through this computerization, the number of answers was laid in multiple choices format not unlike in the past board exams. This is helpful for the examinees because of the advantage of the choices as reference answers during the process of solving the analytical questions. Once the problem is solved by the test-takers, they can match from the given choices which in turn gives them preferable results. Even guessing from the choices can barely come up with the right answer through this format.

By the way, the examination is composed of 100 exam problems where the number of questions for each subject shall not be less than 20. It is a closed book and notes test. The test-takers are given 10 computation and scratch sheets which must be submitted with the answer sheets. Electronic and scientific calculators are allowed except programmable calculators which will be confiscated if brought to the examination room.

## Does solving the past Civil Engineering Licensure examination questions helpful?

Working out the past CE licensure problems is beneficial for the would-be takers.

Why is it so?

Let us try to unravel what is stated in Resolution No. 02 Series of 1995 of the Civil Engineering Law as stated *;*

“The Board shallprovide a minimum of 500 questions for each subject from which the computer of the Commission will select at random on the day or a few days prior to the examination the questions to be given.”

Whereas through gathered previous test data there are exactly identical questions that occurred in other months and years of examination.

This gives an edge to the examinee as the chances of encountering the same questions are probable due to the random selection from 500 questionnaires. Therefore, it is advisable for the examinee to be familiar with past questions.

Arm with this advantage helps you ace in solving the civil engineering board exam questions.

## Overview of how is the board exam administered?

The examination is conducted for two days duration covering the three subjects namely Mathematics, Surveying, Hydraulics, Design, and Construction.

The test is carried out every May and November yearly.

There are various designated testing centers throughout the whole country where the test is administered. It is up to you to select where ever the convenient nominated locations you prefer to choose. Moreover, there is also a special board exam held overseas for those Overseas Filipino Workers (OFW’s) who are willing to attain their certificate of registration.
