■1. Study automatically!

What if you could automatically study one previous Dangerous Materials Engineer exam question every time you turned on your phone?
How often do you turn on your phone each day?

You check KakaoTalk, Instagram, the time, and even just glance at your phone. But if a question popped up every time you opened it, wouldn't you study a lot without even realizing it?

You need to study hard before an important exam. But even if you have a study app installed on your phone, it's a hassle to go back to the app and start studying again. It's often the case that you forget you're studying the moment you turn on your phone.

Just turn on your phone and you'll automatically see flash study cards and previous Dangerous Materials Engineer exam questions. If solving the questions is too much of a hassle, just read through them once and don't worry about making mistakes. Even if you just read the clear explanations once and move on, it's incredibly helpful.

■2. Extensive past exam questions + the latest questions!
We provide all past exam questions from most rounds of the Dangerous Materials Engineer exam, including correct and incorrect answer explanations.

Furthermore, future exams are updated without fail, so this app is all you need to master past exam questions.
This is the most authentic Dangerous Materials Engineer study app you've ever seen, so trust us and get it!

■3. Everything's free
Yes! It's currently completely free.

■4. Unit-by-Unit Focused Study Function
From the first to the last...

Studying the old-fashioned way is very inefficient.

We provide functions that allow you to focus on your weak areas,
and even view them by unit and question type.

■5. Essential study features only experienced students know!
"What did I get wrong? I know this question, but why does it keep appearing?"
"I want to see only the confusing questions..."
Stop worrying about these things.

Create your own app with the error note and problem skipping features.

If you get a question wrong, it's automatically recorded in your error note.

There's even a feature that lets you skip a question you already know completely,
and never see it again.

You can bookmark questions you want to review later,
and view only that part on your lock screen!

■6. Clear and concise explanations, filled with care
We provide explanations tailored to those who study briefly on their lock screen. Our dedicated test-takers provide concise and clear explanations of correct and incorrect answers.

We believe this will be much more helpful than lengthy, tedious explanations.

(Some exams may not have explanations, depending on the qualification or the nature of the questions. We'll continue to add more as needed.)
