  1. I think this is among the most vital information for me.
    And i’m glad reading your article. But want to remark on few general things,
    The site style is great, the articles is really nice :
    D. Good job, cheers

  2. Keep this going please, great job!

  3. Do Children Really Need One-on-One Classes for Preparing for the Mathematics
    Olympiad?

    I was the kind of parent who was skeptical at
    first whenever I heard about private tutoring.
    In my mind I thought: isn’t school already enough?
    My child already gets plenty of homework and after-school sessions from
    teachers.
    So when a friend suggested private OSN Math lessons, I kept
    asking myself: is it really necessary?

    But the experience over the past few months has completely
    changed my perspective.

    What’s the Difference Between School Learning and Olympiad Prep?

    At school, my child appeared smart.
    His math grades were always above average.

    But once he tried to take the school-level OSN selection, he struggled.

    The problems were far more complex, sometimes requiring advanced approaches that
    were never taught in class.

    According to studies from the National Research Council (2000),
    school learning emphasizes procedural knowledge, while Olympiads demand a higher level of reasoning.

    So it’s natural if even bright students at school still find OSN challenging.

    This made me start thinking that maybe a special approach
    really is needed.

    Can Private Tutoring Fill That Gap?

    At first I was skeptical, because I thought private tutoring
    only meant more lessons.
    But it turned out to be not that simple.

    When I signed up at NgajarPrivat.com, I immediately noticed the
    difference.
    OSN tutors don’t just repeat school material — they break down problems in ways that
    help my child see patterns.
    For example, a difficult number theory problem could be explained with a simple analogy.

    According to Bloom (1984), one-on-one tutoring can boost academic performance by up to twice compared to large classes.

    And from my experience, it’s true — my child understood concepts much faster.

    How Did Tutoring Affect My Child?

    The most surprising change was in my child’s attitude.

    Before, whenever he saw OSN problems, he got frustrated
    right away. It felt like he wanted to give up instantly.

    After joining private lessons through KoncoSinau.id,
    he became more confident.
    He said his tutor was very patient, never scolded him for mistakes, and instead gave encouragement.

    That’s when I realized tutoring wasn’t only about material,
    but also about building a child’s mindset.

    According to Dweck (2006), children with a growth mindset are
    more likely to persevere through difficulties.
    Private tutors often nurture this mindset, making students more resilient in facing Olympiad problems.

    Which Is More Effective: Online or Offline Tutoring?

    I tried both options.
    At first, I chose offline because it felt more natural.

    A tutor from LapakGuruPrivat.com came to our home, and my
    child could ask questions face-to-face without worrying about internet
    issues.

    But later, due to schedule conflicts, we tried online classes.

    It turned out to be equally useful.
    The tutor could share screen, write formulas on a digital whiteboard, and
    my child still interacted actively.

    According to Means et al. (2013), online learning is proven to be as effective to face-to-face teaching if designed well.

    So eventually, we decided on a combination: offline for intensive sessions, and online for additional practice.

    Does OSN Tutoring Overwhelm Students?

    One of my concerns was that it might overload my child.

    But actually, with flexible scheduling, it felt lighter.

    Private tutors usually adjust lesson duration to the
    child’s condition.
    If the child gets too tired, they don’t force them, but instead switch to
    a engaging style.
    I once saw my child learning geometry through
    interactive apps — something he never got in school.

    Csikszentmihalyi’s (1990) flow theory shows that when learning is enjoyable,
    kids become more focused and productive.
    That’s exactly what I noticed when my child
    studied with a private tutor.

    Is Private Tutoring a Good Value?

    Honestly, cost was a consideration.
    But after seeing my child’s progress, I felt it was worth it.

    Before, he could only solve 2 out of 10 OSN district-level problems.

    After three months of intensive tutoring, he managed to
    solve 6 correctly.
    Even though he didn’t win, for me that was a huge
    leap.

    I also saw other changes: he became more diligent,
    more patient, and less likely to give up.
    According to research from Universitas Indonesia (Putri,
    2019), participating in academic competitions improves
    resilience and grit.
    So the benefits are not only academic but also
    character-based.

    Where to Find Reliable OSN Private Lessons?

    As a parent, I was careful.
    After research and asking around, I ended up trusting three platforms:

    – NgajarPrivat.com – focused on intensive guidance with tutors experienced in OSN.

    – KoncoSinau.id – flexible for online learning, suitable for busy students.

    – LapakGuruPrivat.com – offers many private tutors, both for Math Olympiad
    and other subjects.

    From my experience, all three are trustworthy, with clear systems and
    skilled tutors.

    Final Thoughts: Was Private Tutoring the Right Decision?

    Not at all. In fact, I’m grateful I took the step.

    Private OSN Math lessons not only helped my child understand complex problems, but also built resilience.

    From being doubtful at first, now I’m convinced this is
    an important investment for my child’s future.

    If other parents are still hesitant like I was, my advice is simple:
    just give it a try.
    Based on my experience, the difference before and after private tutoring is truly remarkable.
