Test Anxiety & Mental Overload: How to Overcome Panic 

When most people encounter a numerical reasoning question, they are overloaded by visual, numerical and textual data. The typical reaction is panic. The thought is they must fully understand every detail at once.

This causes people to feel as if they are facing insanely ‘difficult’ or ‘complicated’ questions. However, in most cases that is simply not the case. So remember to breath.

When solving a numerical reasoning question, address only what's relevant to the question. Don't try to attack an entire army of numbers and words at once. Instead, try to be strategic and take on one problem or variable at a time. It is our mission to teach you how.

 

A few things worth noting before we dive in:


1) Time is everything: There is no complex math in numerical reasoning tests. The difficulty lies in the short 45-75 seconds solving time given per question.

Most of the strategies you'll see on this page will help you shorten your solving time.

2) Estimation is key: Frequently, numerical reasoning tests are presented in multiple-choice. Therefore, estimation is key and an answer close enough is good enough!

3) Strengthening your mental muscles is a MUST: Forget about ‘you either have it, or you don't’. More than any other type of aptitude test, numerical reasoning crucially depends on training and practise.

You train, you get better - it's simple maths.

The format of multiple-choice questions combined with rigorous time constraints gives an advantage for those who practise seriously.

Tackling Numerical Reasoning Questions: The JobTestPrep Method

This is our personal 'world famous' method to completely destroy most numerical reasoning questions.

It consists of 4 stages:

  1. Detect – what is the question asking
  2. Observe – separate the relevant from the irrelevant information
  3. Focus – focus on the relevant information and perform the necessary calculations
  4. Eliminate and Solve – use estimations and quick calculation methods to eliminate incorrect answers and solve the question

Let's take a look at an example:

 

In the year 2000, the Product Development department constituted 400 employees.

How many employees worked for the Stamping department in that year?

A. 400

B. 450

C. 500

D. 550

Let's break the solving process by implementing the 4 stages of DOFE:

When we're asking about the number of employees in the Stamping department in 2000.

The relevant information is:

  • The data from the year 2000.
  • The number of employees in the product development department
  • The number of employees in the stamping department

Thus, the question turns to:

 

Quite a difference, isn't it?

 

Let's set the information we have in a table:

  Product Development Stamping
Percentage of Employees 20% 25%
Number of Employees 400 ?

Since the calculation is very straightforward, we will not eliminate and look for the solution:

Using ratios:

(400/20) = (?/25)

? = 20 x 25 = 500

The number of employees in the stamping department is D (500).


Let's try another example:

In Hungary, each person received 12 letters per month on average.

How many letters a month did people who don’t own a post office box receive in total if no two post office boxes are owned by the same person, and those who own post office boxes always get their post delivered to their post office boxes?

A. 182,198,000

B. 121,037,832

C. 142,936,000

D. 120,206,448

 Try using our 4 stages again:

We're asked to find all the people in Hungary who DO NOT get mail by a post office box (POB), and multiply it by the number of letters.

The relevant information is:

  • The total number of people in Hungary
  • The number of people who DO get their mail by post office boxes
  • The number of letters each person receives per month

Thus, the question turns to:

Number of letters per month: 12.

Now let’s break this whole lot of verbiage, intended to confuse you, to what it basically means:

... if no two post office boxes are owned by the same person, and those who own post office boxes always get their post delivered to their post office boxes?

  • No two post office boxes are owned by the same person:

Number of people who own POBs = Number of POBs

  • Those who own post office boxes always get their post delivered to their post office boxes:

All mail received in POBs in Hungary = Number of POBs x Number of letters

Now when we know all this, let's set a calculation plan:

[(All People in Hungary) - (People Who Have POBs)] x (Number of Letters per Month) =

Eliminate and solve – again, we have a complete drill to just plug numbers into, so let’s do it:

[10,100,000 – 82,796] x 12 = 120,206,448

Thus, the correct answer is D (120,206,448).

Again, we have a complete drill to just plug numbers into, so let’s do it:

[10,100,000 – 82,796] x 12 = 120,206,448

Thus, the correct answer is D (120,206,448).

Numerical reasoning Solving Techniques without a Calculator

Solving Techniques When You Can't Use a Calculator

Facing a test without a calculator is like facing a dragon without a sword. For such a frightening occasion we'd like to equip you with mathematical techniques used while solving problems calculator-less. Good luck!

 

1) Multiplication by 5

When you need to multiply a number by 5, divide it first by 2 and then multiply by 10.

Example:

168 x 5 = ?

168 X 5 = (168 /2) x 10 = 84 x 10 = 840.

The correct answer is 840.


2) Use the Last Digit for Multiplication

Looking at the last digit of a multiplication can help you get to the correct answer without calculating.

Example:

123 x 429 = ?

A) 50,222

B) 52,767

C) 63,448

D) 55,409

Multiplying the last two digits of the exercise:

3x9 = 27, so the last digit of the result must be 7.

It's clear that the answer is B (52,767)

 


Try another example:

747 x 559 = ?

A) 434,413

B) 420,063

C) 417,573

D) 557,433

In that case, the last digit trick will not help, since all answer choices end with 3. So let's calculate the 10's digit, using this simple trick:

747 x 559

7x9 = 63

7x50 = 350

40x9 = 360

6 + 5 + 6 = 17

 

That means our 10's digit is 7. Note that it's not 1, since the 1 will be added to the 100's digit.

The only answer choice which satisfies both conditions is (417,573)


3) Estimate Compound Growth Without a Calculator (Advanced Technique)

Use first-order and second-order elements to closely estimate growth/decrease.

Example:

You put £1,500 in the bank on the beginning of 2010. How much will you have by 2020 if the interest rate is 5%?

A) £1,750.25

B) £2,225

C) £2,355.60

D) £2,443.20

The correct answer is (£2,443.20)

 

The formula for calculating compound growth is:

 

Final=Initial∙(1+i)^N

 

Where:

i = growth rate (in our case – 5% = 0.05)

N = number of periods (in our case – 10)

 

Final=1500∙(1.05)^10

 

It is evident that this calculation is quite long to do without a calculator. Therefore, we will use the following trick:

1. Calculate the first-order-approximation:

FOA=1+i∙N

FOA = 1 + 0.05 x 10 = 1.5

1st estimate: 1,500 x 1.5 = 2,250

 

2. Check if the estimation is close enough to reach the answer. In our case, answers C and D are rather close to the estimated answer. Thus, we will have to move on to step 3:

 

3. Calculate the second-order approximation and add it to the result:

SOA=(N∙(N−1))2∙i2

SOA = [(10 x 9)/2] x 0.052 = 45 x 0.0025 = 0.1125

2nd estimate = 2,250 + 0.1125 x 1500 = 2,250 + 168.75 (you could very well estimate at 165 here, too) = 2,418.75

 

Thus, it becomes clear that the correct answer is D.

numerical reasoning test tips and tricks

Expert Tricks to Help You Avoid Unnecessary Calculations

The biggest problem that many face during numerical reasoning tests is the time limit.

Learning how to draw conclusion quickly enables you to answer more questions accurately and confidently.

 

1) Ignore multiplication factors

If you multiply and then divide by the same number, it can be ignored altogether.

Example:

A family's monthly petrol expense in year 1 is £250.  What will be the percentage change of their annual petrol expense in year 2 if their monthly expense is £180?

To thoroughly calculate, we'd begin:

Annual expense in year 1: £250 x 12 = £3,000

Annual expense in year 2: £180 x 12 = £2,160

 

The change in percentage:

Change = [(3,000 – 2,160)/(3,000)]x100% = 28%

 

To calculation quickly, we'd begin:

Notice that in order to change the monthly expense to annual expense, we multiply by 12 and then divide by it:

 

Change = [(250x12– 180x12)/(250x12)]

Which is basically the same as:

Change = [(250-180)/(250)]x100% = 28%.

 

2) The '-1' percentage calculation

If you're looking for a change in percentage, take the ratio values and subtract one.

Example:

Looking at the question in the previous example, we could have just written:

Change = (180/250)-1 = 0.72-1 = -0.28

That means a decrease of 28%.

Did you notice we did not multiply by 100%? That is also a small tweak that can save you quite some time when accumulated.

Remember to convert decimals into percentages, move the period twice to the right:

0.28 → 28%

0.05 → 5%

2.36% → 236%

 

3) Create a calculation template 

This might seem like a long process at first, but if you practise to perfection, it will save you valuable calculation time.

Create a framework in which you enter all your calculations, so eventually, you calculate only once.

 

Example:

Government Construction Contracts (%)

Of 400 contracts were offered for £22,200 each.  In 2009, contract value increased by 7%, and there was a 25% decrease in the number of contracts.

How much more money than Buildingo did Roads do in 2009?

A. 192,543

B. 217,386

C. 321,654

D. 423,964

E. 213,786

The correct answer is E (213,786)

1. Create a template. Since the question asks, ‘How much more …’, it would look like:

Answer = IncomeRoads - IncomeBuildingo

 

2. Break each part of the template into smaller parts:

Income = NC ⋅ PC

NC = TNC ⋅ Share(%)

 

Where:

TNC = Total Number of Contracts

NC = Number of company's Contracts

PC = Price per Contract

Share = Company's share of the contracts (from the graph)

 

So the final template will look as follows:

Answer = (TNC ⋅ Share ⋅ PC)Roads - (TNC ⋅ Share ⋅ PC)Buildingo

 

3. Identify common multipliers to minimize the template

      • We know that the price per contract PC is similar in all cases:
        PC = £22,200 x 1.07 = £23,754.
      • We know that the total number of contracts TNC is 400 x 0.75 = 300.
      • The only difference between Roads and Buildingo is their share:
        Buildingo has a share of 9%, Roads has a share of 12%.

 

4. Rearrange, plug in numbers and calculate once.

Now, after rearranging the numbers, our template will look like:

Answer = (300 ⋅ 23,754) x (0.12 - 0.09) = 213,786


General Tips for Numerical Reasoning

Numerical aptitude tests rely on basic mathematical concepts that can easily be reviewed and memorised. This includes the four operations (+, -, x, /) upon which further concepts are applied, like percentages, averages and ratios. 

To succeed, you must master these basic concepts while drilling down into the complex questions of graphs and tables, number series and word problems.

Don't try to solve the entire question nor understand the load of information presented before you. Focus on the question, and apply only the relevant, useful data.

Since most numerical tests use some sort of graphs and tables to present information, you should get used to reading this type of data:

Financial sections of daily newspapers and, of course, practice questions and sample tests are the best way to familiarise yourself with possible types of data presentation.

Pay attention to units and scales. It is very common to find questions where the information is presented in millions when the question actually refers to thousands.

Pay attention for comments, asterisks, etc. They are easily missed and are often crucial to solve the questions.

Use the orientation test: After a few seconds of scanning the data, place your finger somewhere on the data area and explain that piece of data.

Know in advance if you're allowed a calculator and prepare accordingly.

  • No Calculator Allowed: Improve your basic numeracy calculations, as they might be the difference between failure and success.
  • Allowed to use a Calculator: Learn to skillfully know your device. Using your calculator wisely can become a substantial time saver. For instance, people who are not accustomed to using a calculator tend to write each result instead of leaving it on the calculator's screen for the next calculation.

 

Improve your score within just a few days - with test prep specifically tailored after the test employers use.

What to Do About Test Anxiety

Despite preparation, oftentimes people feel stressed before entering an exam. In these cases, it's best to breathe and remember that you previously prepared.

If you are known to have test anxiety, be sure to get a full night's sleep and eat a proper meal.

Twitching moments before the test is also common. In these cases, massaging your pencil hand can help calm you and, if you have enough time, try stretching.
