■1. Study Automatically!

What if you could naturally study one past Hazardous Materials Class 4 exam question every time you opened your smartphone?

How many times a day do you open your smartphone?

We often look at the screen for YouTube, Instagram, the time, and even casually, but if a question appeared every time we opened it, we'd study a lot more without even realizing it.

You need to increase your study time before an important exam. However, even if you download a study app to your smartphone, it can be a hassle to constantly search for the app and pick up where you left off last time. What's more, the moment you turn on your smartphone, you often forget that you even need to study.

Simply turn on your smartphone and past questions from the Hazardous Materials Class 4 Examination will automatically appear. If you don't want to bother with solving the questions, just read them. They also come with easy-to-understand explanations, so even a quick glance can be very helpful.

■5. Intensive Study Function by Unit
Studying in general terms from the first question to the final question is extremely inefficient.
We offer a feature that allows you to view questions by number of attempts, so you can focus on studying only the areas you're weak at.

■6. Packed with essential features that only experienced students will understand!
"Where did I get it wrong?" "I know this question, so why does it keep coming up...?"
"I want to see all the questions I got wrong..."
Eliminate these worries and create the perfect app for you with the Mistake Note feature.

Questions you get wrong are automatically saved to your own notebook.
You can also organize questions you fully understand into "Understood" and hide them from view.
You can also favorite questions you want to see again in the future and view only those sections on the lock screen!

■7. Carefully crafted, clear, and concise explanations
We provide explanations perfect for those who study little by little on their lock screen.
Our exam instructors have carefully provided concise, clear, and comprehensive explanations of correct and incorrect answers.

We believe these explanations are far more helpful than lengthy, long, or difficult-to-read explanations. (Some qualifications and questions may not have explanations. Explanations are being added regularly.)
