This course is based on my many years as a college lecturer of mathematics and seeing how many students have received so much misguided information on percentages in their previous schooling.

Many students who I have taught are able to grasp the concepts quickly and are able to solve many related problems.


Now just imagine how you are going to feel once you have finally worked out how to deal with percentages.

Whether you are a student looking to improve your math skills or a parent trying to teach your own children, any feelings of being overwhelmed just by looking at percentages is going to disappear. The entire experience is going to be quick, easy and it is also going to be fun.

Once you have completed this course it really will have an impact on your performance in school but also in the real world as percentages are used in my scenarios.

In this course you are going to master the following skills:

  • Be able to define what a percentage is
  • Understand the relationship between fractions and percentages
  • Be able to use multiple methods to answer percentage questions
  • How to quickly determine the profit or loss of anything using a simple formula
  • And more....


This is what some of my private student's have said about my teaching ability:
