Preparation brings good result. That is the famous proverb that shows the importance of preparation. In this case, it is always important to make preparation. Proper preparation will be necessary to make sure that all things can be done and executed well. The same things happen for the case of math Olympiad. It is true that there is such an Olympiad for mathematics. Actually, there are also same championships for other subjects, so it is not only for mathematics. In this championship or competition, complexity of problems are different from what students usually find in daily or regular subjects.
It is true that complexity and level of difficulties are different. Even, it can be said that these are completely in different level. Those who have great scores in mathematics class do not mean that they will get good ranks or scores in the math Olympiad. It is because the tests and problems need more than just easy and simple solution or problem solving.
In the Olympiad, what is needed by students is about analytical skills to know the problems and how to solve it properly. The tests may look simple, but it needs more than just a single step to finish it.
In this case, preparation is important. It is impossible that there are students who can get good scores and ranks in the Olympiad when they have no preparation. That is why it is important and this cannot be neglected. The preparation covers several points.
It is not only to study the materials, but the most important is to master the logics and understanding. Then, they need to have many practices. In this case, there are some sources that can be accessed to get some questions for the math Olympiad. These can be used to get the questions for practices. Of course, it is also important to focus on weak area.
