틈틈한국사-수능 (기출문제+ 해설, 잠금화면 시험공부)

***There are Korean (SAT), Intermittent English (SAT), Intermittent Korean History (SAT), Intermittent SAT-Life and Ethics, Social Culture, Korean Geography, World Geography, and Korean Skill Sword, so please use it once!***

■1. Study automatically!
What if I study Korean history automatically every time I turn on my phone?
How often do you turn on your phone per day?
Checking KakaoTalk, checking Instagram, Facebook, or even subconsciously opening the phone once, but every time you open the phone, one problem appears, you will learn a lot without realizing it, right?

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 previous questions about Korean history automatically just by turning on your 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. 10 years' worth of previous questions + up to the latest questions!
Korean history of the SAT, designated as mandatory from the 2017 SAT,
We provide all 5 years' worth of mock exams + past CSAT questions, correct answer explanation + incorrect answer explanation, without omission. And the exams to be conducted in the future will be updated immediately, so this one app is enough to conquer previous questions!

It's a really good Korean history study app that you've never seen before, so trust and get it!
(Even if you do not necessarily prepare for the Korean history exam, you can solve it in a fun way to build common sense if you are interested in history.)

■3. All of this is completely free
Yes! It's completely free.
Do not pay for more than a few or sell in-app.
All content is completely free.

■4. Intensive learning function by theme/category
From the first to the last... from the Paleolithic to the modern...
Go study with your fists!
so that I can focus on studying only the areas where I am weak
It is provided by era and by theme.

■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...'
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.
Korean history specialists carefully
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.

*** Notifications related to app capacity / data usage ***
All problem image files are stored in the app, so you do not have to worry about image file data when using it normally.
However, please note that the size of the app has increased as the amount of problems is huge.


We worked really hard to make the app.
If you introduce a lot to your schoolmates and more people use it, you will get greater power to improve functions or add content.
We would be very grateful if you could introduce us on Facebook, KakaoTalk, Instagram, etc.
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.
