There are only two kinds of advantage you can give your child in any test or competition. One is information and the other is a set of fluid skills.
Information is test-specific. For example, the test syllabus or the typical questions that come out in the previous years. Sometimes there are loopholes with the way a test is designed, and test specialists know how to exploit it. In general, information helps your child to save time before and during the test.
On the other hand, fluid skills are evergreen skills that can be used in all problems across all tests. If you know someone who does not seem to prepare much but still doing well, most likely they have some of the fluid skills.
Our lessons are designed to give both information and fluid skills to your child.
