Strategy for Numerical Ability

Here are some strategies to improve your numerical ability:

Before the Test:

Brush up on the basics: Make sure you're comfortable with fundamental math operations like addition, subtraction, multiplication, and division. You should also be familiar with percentages, decimals, and fractions.

Practice with sample questions: There are many resources available online and in libraries that offer practice questions for numerical reasoning tests. Familiarize yourself with the different types of questions you might encounter, such as percentages, averages, ratios, and data interpretation.

Identify the test provider (if possible):  Some companies use specific test providers for numerical reasoning assessments. If you can find out which provider is being used, you can target your practice to their question style.

Learn about common question types:

Percentage problems: These involve calculating percentages, discounts, markups, and increases/decreases.
Ratio problems: These involve understanding relationships between quantities.
Averages: Be comfortable with finding the mean, median, and mode of data sets.
Data interpretation: This might involve interpreting charts, graphs, and tables to answer questions.
Sharpen your estimation skills: In many cases, particularly under timed conditions, getting an exact answer isn't crucial. Learn to estimate answers to quickly eliminate obviously wrong choices.

During the Test:

Read carefully: Don't rush into calculations. Make sure you understand what the question is asking before you start solving.
Manage your time: If you get stuck on a question, don't waste too much time. Move on and come back to it later if you have time.
Use a calculator (if allowed): Unless specifically prohibited, using a calculator can save you time and reduce errors. However, make sure you know how to use it effectively.
Show your work (sometimes): While some tests may not require this, writing down your calculations can help you identify errors and jog your memory if you need to come back to a question.
Double-check your answers: If you have time left, review your answers for any careless mistakes.
Additional Tips:

Stay calm and focused: Test anxiety can cloud your judgement. Take a few deep breaths and focus on the task at hand.
Practice mental math: There are exercises you can do to improve your mental math abilities, which can be helpful for quick calculations.
Build your confidence: The more you practice, the more confident you will feel in your numerical abilities.
By following these strategies and practicing regularly, you can significantly improve your performance on numerical reasoning tests.
