What is the CAST Aptitude Test?

The CAST is a test used to measure a candidate's ability to process information quickly, solve basic math problems, and solve different aptitude tests. 

Here is a table summarizing what the test consists of:

The actual CAST test questions are not overly hard. However, you have to do the math with a pen and paper instead of a calculator, and there is a strict time limit: These facts mean that the math and mechanical tests can cause a lot of test anxiety and performance issues.


CAST Test Scoring

The CAST tests are not standardized tests: each company has its own standards and can choose any pass mark. In addition, depending on the number and level of candidates the passing score can be changed. This means that to pass, you have to be better than the average test taker. But how much better?

In general, the CAST aptitude test pass score - is in the upper 20%. So, you have to be better than 80% of test takers to pass.

CAST Sample Questions

Graphic Arithmetic Test

In the CAST Graphic Arithmetic Test, you have 30 minutes to answer 16 questions. It measures your ability to solve arithmetic problems by using information from drawings. 

You will be presented with a top-down diagram of a building. This building has lots of measurements and different rooms inside. There are, however, some measurements missing. It is your task to calculate these numbers in order to answer the questions without the use of a calculator.

The questions are multiple-choice, with five different answers.

The questions will all relate to two images. However, each image has eight separate questions relating to it. Since this is the case, it’s important to remember that you may use the answers to the previous questions in order to help you answer the current one.

Let’s take a look at a CAST sample question. Try solving this one in two minutes- that's how much time you'll have during the test:

 

The length (top to bottom) of the total property is ____ times larger than the length of the nurse's room.

A. 3
B. 3 1/2
C. 3 1/3
D. 3.6
Correct Answer
Incorrect Answer

The correct answer is C.

To find the ratio between these two values, divide the length of the total property (90') by the length of the nurse's room (27'). Note that both numbers can be divided by 9:

 

What’s particularly difficult here is that you cannot use a calculator in this section of the CAST exam. You need to know how to do a variety of different calculations including long division in order to answer this question correctly without having to guess. That’s why, on this PrepPack™, we have included super clear instructions on how to carry out these calculations.


Mathematical Usage

The Mathematical Usage test measures your ability to solve basic mathematical problems from provided information. You will be presented with a table with a number of different relationships- for example, the number of grams in a tonne. You have to use this table in order to answer questions based on this information.

The actual test has 18 questions with a 7-minute time limit. This is a short time limit and really requires a high level of attention. Getting a full score on this test is possible: You just need to learn how to really focus on what’s being asked and how to solve it.

Let’s take a look at a sample question. During the real test, you will have 23 seconds.

1 fathom = 6 feet

1 mile = 5,280 feet

0.5 miles = ? fathoms

As above, there are no calculators allowed in this test. 30 seconds per question is really steep and although you may be able to answer all the questions, doing so within the time allotted is going to be a steep challenge. This is why it’s absolutely imperative to give yourself the practice and preparation that you need in order to succeed on the CAST test.


Mechanical Concepts

In this CAST assessment, you are tested on your understanding of mechanical concepts and principles. These principles include:

  • Centrifugal Force
  • Gears
  • Gravity
  • Levers
  • Pulleys
  • Shapes

 Among others. For each question there are three possible answers and, as with all the other sections of the CAST assessment, you have to work fast in order to answer all the questions within the allotted time. 44 questions in only 20 minutes gives you less than 30 seconds per question. That’s why preparation is so key here. It’s not only knowing the principles, it’s answering the questions quickly enough to get through them all in the allotted time.

Let’s take a look at a sample question- during the real test, you will have 27 seconds to answer.

In which of the following positions would the tractor be less stable when taking a turn?

CAST free test

 

A
B
The same
Correct Answer
Incorrect Answer

The correct answer is B.

As you can see, the only difference between the two figures is the position of the tractor's shovel. In figure A the shovel is lowered, while in Figure B the shovel is raised. The raising of the shovel will also raise the point of the center of mass of the tractor. When the center of mass of the tractor is higher, the tractor loses some stability (A good example could be the difference between a semi-trailer and a sports car. The tall and narrow semi-trailer has a higher point of center of mass and is less stable than the low lying, flat and wide sports car which has a lower point of center of mass).

 

Since in Figure B the shovel is raised, it is less stable. Therefore, choice B is the correct answer.

Reading for Comprehension

In this CAST aptitude test you have to answer 32 questions in a 30 minute time frame.

You are presented with four different passages and for each passage you have to answer eight questions. These passages are long and take some time to read. Whilst it may seem worthwhile to just scan through the paragraphs, it isn’t really advisable as you have to answer eight questions on it. Trying to take everything in is therefore a good idea in this situation. There are four different answer options for each of the questions.

Let’s take a look at an example question:

Static Electricity

Most of us remember a painful incident when sparks blasted our hands after touching metal objects. Do you remember the game we used to play as kids where we would rub a balloon against a wool sweater and then see if the balloon would stick to the wall? These are examples of "static electricity." Though static electricity is a common phenomenon, its cause is often misunderstood.

Static electricity can result from the friction of two objects rubbing against each other, like the sole of your shoes against the carpet. However, friction is not required for static electricity to occur. It is a common misconception that friction is required to create static electricity. It is true that friction can increase the likelihood of static electricity, but it is not the cause. The true cause is the separation of negative and positive charges.

Every object is composed of a collection of positive and negative electric charges. Usually, the number of positive charges and the number of negative charges is equal. Static electricity (more correctly called "net electric charge") occurs whenever the number of positive and negative electric charges is not perfectly equal.

Let's take the example of walking across a carpeted room. When we walk, the soles of our shoes absorb some negative charge found in the carpet. We leave behind electric positive footprints, and our bodies acquire some negative charges. This process goes on for some time until our body achieves a high level of negative electric charge. The next time that we touch someone or some object, we will get zapped as the imbalanced charge is shared between us and the other person or object. The spark is painful because it is extremely hot. It creates tiny burned areas on our skin that hurt for a couple of seconds.

There is a simple way to avoid shocks caused by static electricity. Before touching objects such as a doorknob or a car door, first touch the object with a car key. The static electric sparks will blast the key rather than your hand and will painlessly discharge from your body. After the static electricity has been discharged, you can safely touch metal objects. Of course, if you walk around on the carpet again, you will once again acquire static electricity.

According to the passage, how common is "static electricity"?

It is very common
It is quite rare
It happens only in winter
The paragraph does not provide sufficient information to answer this question
Correct Answer
Incorrect Answer

Explanation: A is the correct answer. The fourth sentence in the first paragraph states that "Though static electricity is a common phenomenon...."

 

 

As you can see, the passage, for reading comprehension is very long at over 300 words. It’s very worthwhile for you to get to grips with such passages and learn how to answer these questions. Unfortunately, it’s easy to get distracted by long texts and that is why practice really does make perfect.
