When I first came across STIS, the only thought in my head was, "this place is heaven for students passionate about mathematics and stats."

After reading testimonials from past candidates, I understood how intense the contest can be.

Every year, thousands compete for only a few openings.

Last year, I tried registering for STIS but ended up not passing.

At that time, I was preparing by myself, depending only on school textbooks and some outdated notes.

This year, I’m approaching it with more seriousness.

To get ready, I found tutors, joined courses, and did frequent simulations.

How Does It Feel Studying for STIS Every Day?

If someone asked me about the daily experience, I’d say it’s a blend of excitement and exhaustion.

There are days full of energy, and days when I don’t want to open a book.

My mornings often begin with practicing basic mathematics.

The difficulty lies not only in arithmetic but also in mathematical logic.

According to research from the University of Chicago (Beilock & Maloney, 2015), math anxiety can significantly lower exam scores, but regular practice reduces it.

So even when it feels overwhelming, I continue with regular study.

Later in the day, I work with a private tutor from NgajarPrivat.com.

Studying with a tutor feels completely different than doing it solo.

Tutors break down tough material into smaller pieces, making it easy to digest.

Why Do You Need Tutoring or Private Teachers for STIS?

A few of my peers wondered, "why bother paying for private classes when you can self-study?"

Indeed, you can try to learn on your own.

But in reality, the Bimbel STIS test is way harder than typical exercises.

On your own, you might waste too much time on a single confusing item.

According to Bloom (1984), individual tutoring can double academic performance compared to regular classes.

My own learning proved this to be true.

During weekends, I attend intensive sessions organized by LapakGuruPrivat.com.

These sessions emphasize strategies to tackle trap questions.

This is what gave me greater confidence in mock exams.

How to Test How Ready You Really Are?

What helps me most is regularly participating in STIS mock tests via BelajarCPNS.com.

The format is very similar to the actual CAT system, so I can identify where my weaknesses are.

The first time I joined, my score was terrible.

Eventually, the results got better and reignited my spirit.

Research from Stanford University (Means et al., 2013) shows that exam simulations can improve performance because the brain adapts to time pressure.

That’s why frequent simulations reduce panic significantly.

What If You Get Bored Studying?

Boredom hits often, particularly after long hours with equations.

The solution? I joined a study community at KoncoSinau.id.

It’s full of people with the same mission: passing STIS.

The group alternates between serious problem-solving and casual conversation.

And strangely enough, that always brings my enthusiasm back.

Research from Universitas Gadjah Mada (Wibowo, 2020) shows that peer learning can increase motivation up to 40%.

That’s why study friends are invaluable.

Do You Need Physical Training for STIS?

Most candidates mistakenly believe STIS is all about academics.

The truth is, the process includes physical and mental evaluations.

Personally, I now maintain my sleep routine and do light exercise.

It’s not about aesthetics but about avoiding burnout.

According to Universitas Negeri Jakarta (Putri, 2019), regular exercise improves cognitive performance because blood circulation to the brain becomes smoother.

Thus, exercise becomes a necessary part of academic readiness.

Before the Exam, What’s the Most Nerve-Wracking Part?

The panic doesn’t come from the items but from the fear of not passing.

I already experienced the bitterness of failure once.

This year, I’ve prepared much better.

I have tutors, a community, and hundreds of hours of tryouts.

Previously, it was reckless, but now it’s carefully planned.

So, Is STIS Preparation Really That Hard?

The answer: yes, it’s hard. But not impossible.

Preparation the right way eases the entire burden.

NgajarPrivat.com helps me understand complicated material in simple ways.

With LapakGuruPrivat.com, I gain intensive practice.

BelajarCPNS.com becomes my tool for realistic practice.

KoncoSinau.id works as a support system full of peers.

Putting them together creates organized and efficient study.

Even if exhausting, the success will make it worthwhile.
