  How to Best Prepare Children for the National Science
  Olympiad in Mathematics
  
  This inquiry often comes up by many parents I’ve met, even from
  fellow teachers. The Mathematics OSN is known as
  a extremely rigorous competition, with problems that demand higher-order reasoning.
  So, what is actually the best way to prepare children for this competition?
  
  I personally had an experience when my friend’s younger brother tried to join the Mathematics OSN at the district level.
  At first, he studied the conventional way: solving practice problems, reading books, and discussing with friends.
  
  But the results were not very satisfying. After trying intensive tutoring through
  a private teacher, the results were completely
  different.
  
  Is OSN Preparation the Same as Learning Math at School?
  
  
  One thing that must be understood: preparing for OSN is not the same as learning math daily at
  school.
  
  According to research from Stanford University, competition-based learning
  demands higher-order thinking skills that differ from regular classroom learning (Resnick, 1987).
  
  OSN emphasizes analysis, creativity, and the ability to connect concepts across topics.
  
  
  That’s why students who rely only on school lessons often feel overwhelmed.
  They need different strategies—and this is where guidance from private tutors such as those at
  NgajarPrivat.com becomes extremely helpful. OSN tutors are used to giving more challenging
  exercises, not just ordinary school exam problems.
  
  
  Why Are Private Tutors More Effective for Olympiad Preparation?
  
  I once talked with a private tutor from KoncoSinau.id who has been mentoring
  Olympiad students for more than ten years. He said that many
  kids are already smart, but without the right guidance, they are like
  “lost” in the jungle of Olympiad problems.
  
  This aligns with research from the Educational Testing Service
  (ETS), which showed that personalized learning improves conceptual understanding by up
  to 30% compared to large classrooms (Bloom, 1984).
  Private tutors can quickly identify student
  weaknesses—whether in number theory, combinatorics, or geometry—and
  address them through a personalized approach.
  
  I still remember when that student failed on a solid geometry problem.
  His private tutor didn’t just teach formulas for
  volume but also connected it with 3D visualization. With that approach,
  the child understood much faster.
  
  What’s the Difference Between Online and Offline OSN Private
  Lessons?
  
  Another classic question is: which is better, online or offline OSN tutoring?
  
  
  From my experience, both have advantages. Offline (face-to-face at home) offers comfort and full focus.
  Meanwhile, online provides access to the best tutors from different cities.
  
  
  
  Research from MIT shows that blended learning (a combination of online and offline) produces better
  learning outcomes compared to a single method (Means et
  al., 2013). So the issue isn’t which is better, but rather how comfortable the child feels and whether they can stay consistent.
  
  
  At LapakGuruPrivat.com, for example, there are options for tutors to come to the house for children who need direct guidance,
  and Zoom/Google Meet sessions for those in other cities.
  From my family’s experience, this flexibility is very
  helpful, especially when OSN preparation time is tight.
  
  
  How Important Is Practice in OSN Preparation?
  
  Practicing problems is indeed important, but it’s not just about the quantity
  of problems. According to research by Ericsson et al.
  (1993), what matters more is deliberate practice—practice that is structured and comes with direct feedback.
  
  
  I personally witnessed how my friend’s younger brother
  used to complete 50 OSN problems in a week, but his progress was slow.
  Once he joined an intensive program at NgajarPrivat.com, the number of
  problems became fewer, but each one was discussed deeply with different strategies.
  As a result, he quickly learned to recognize patterns.
  
  Private tutors usually have OSN problem banks from previous years, and even international Olympiads.
  This allows students to become familiar with various levels of difficulty.
  
  
  
  Can OSN Tutoring Shape a Child’s Character?
  
  Many parents think private tutoring is only for academic improvement.
  But from my experience, OSN preparation also helps build
  character.
  
  According to a study from the University of Indonesia, Olympiad participants have higher levels of grit and
  resilience compared to regular students (Putri, 2019). This is because they are used to facing tough problems and
  not giving up until they find the answer.
  
  I personally saw the student I mentored become more patient, more diligent, and more
  confident after attending OSN private lessons.
  So the benefit is not only winning competitions, but
  also developing traits that carry into everyday life.
  
  Which OSN Math Tutoring Platforms Can Be Trusted?
  
  Nowadays, there are many tutoring platforms, but from my personal experience, three are worth recommending:
  
  – **NgajarPrivat.com** → Ideal for intensive guidance, especially for students who prefer face-to-face interaction.
  – **KoncoSinau.id** → A great option for students who are more comfortable with online learning,
  supported by flexible and experienced tutors.
  – **LapakGuruPrivat.com** → Offers various OSN subjects, not only mathematics.
  Perfect for families with children who have different academic interests.
  
  
  All these platforms have proven successful in helping many students
  reach the national stage. Interestingly, many of the tutors are OSN alumni or
  top university students from places like UI and ITB.
  
  Conclusion: Should Students Take OSN Private Lessons?
  
  If asked whether it’s mandatory, the answer is no. Many outstanding
  students succeed through self-study. But in terms of time efficiency, the right strategies, and
  higher chances of success, OSN private tutoring is
  clearly a wise choice.
  
  With guidance from experienced tutors on platforms like NgajarPrivat.com, KoncoSinau.id, or LapakGuruPrivat.com, students are not only ready to
  tackle Olympiad problems but also equipped with the mental strength
  to face future academic challenges.
  
  In my view, this investment is absolutely worth it.
  Because in the end, OSN is not only about winning medals, but also about shaping a young generation ready to compete at the global level.
