■1. Study automatically!

What if I study 1 question from the previous exam for the welding technician and special welding technician exam automatically every time I turn on my phone?
How often do you turn on your phone per day?
Kakaotalk check, Instagram, time check, and even unconsciously open the phone once, but every time you open the phone, one problem is shown, you will learn a lot without realizing it.

You have to study a lot before an important exam. However, even if I have a study app installed on my phone, it is really annoying to find the app and search it again from the first place I saw it. Even when I turn on my phone, I often forget that I have to study.

You can see the welding technician, special welding technician flash learning card, and previous questions automatically just by turning on the phone. If solving a problem is cumbersome, read it through and feel free to make any mistakes. It is a great help if you read the clear explanation and read it only once.

■2. Extensive previous questions + up to the latest previous questions!
We provide all correct answers + incorrect answers to most of the previous questions for welding technicians and special welding technicians.
And the exams to be conducted in the future are updated immediately, so this one app is enough to conquer previous questions.
It is a really good welding technician, a special welding technician learning app that you have never seen before, so trust and receive it!

■3. All this for free
Yeah! It is currently completely free.

■4. Intensive learning function for each unit
From the first to the last...
Studying like a fist bump is very inefficient.
so that I can focus on studying only the areas where I am weak
Provides a function that can be viewed by unit and problem type.

■5. Essential study functions that only those who have studied can know!
'What did I do wrong? I know this problem, but why does it keep coming up...'
'I want to see only the confusing problems...'
Stop worrying about this
With incorrect answer note function and problem subtraction function
Create an app that's right for you

If you make a mistake, it is automatically recorded in the wrong answer note.
If you are completely aware of a problem, leave it as a known problem.
There is also a feature that prevents you from seeing it again.
Bookmark questions you want to see again later
Only that part can be seen again on the lock screen!

■6. Clear and concise explanations full of sincerity
To those of you who study for a while on the lock screen
It provides the perfect explanation.
The exam springs are sincere
Concise and clear correct answer/wrong answer explanation
It is served generously.

Rather than lengthy and lengthy commentaries, tiring to read
I think it will be much more helpful.
(There are cases where there is no explanation depending on the qualifications and the nature of the problem. We continue to add them as needed.)

We worked really hard to make the app.
If you introduce a lot to people around you, and more people use it, you will get more power to improve functions or add content.
I would be very grateful if you could introduce me through KakaoTalk or Instagram
The +1 button on Google Play will also be appreciated.
If you give me a good review, I will be grateful and accept it as a word to do better.
