A book created with the heart of a test taker - Sina Gong

■ We tried to make it possible to acquire it in the shortest possible time.
As it is designed for the purpose of obtaining a certificate, we excluded content that is theoretically important but has nothing to do with the exam questions.
In addition, we analyzed all the past exam questions by type to determine the level at which a passing score is possible, and boldly excluded content with a low percentage of questions, and clearly marked important content, so that you can deal with any variation of questions that may appear, and explained them in as detailed and easy-to-understand terms as possible.

■ I tried not to feel frustrated while studying.
The written computer skills test is a theoretical exam, but many questions require knowledge of Windows 10 and Excel functions.
Memorizing all the program functions to solve these problems is a very tiring task.
For content requiring practice, we've added detailed step-by-step instructions so that even students with no prior knowledge in this field can learn by following along on the computer screen.


■ Video lectures are provided.
The Sina Gong Computer Proficiency Level 2 written textbook is composed of detailed and easy-to-understand explanations so that even beginners in computer science can study with ease. However, depending on the test taker's situation, they may experience difficulties in learning.
For these people, we provide video lectures on the difficult parts of the textbook.
Scan the QR code in the text to access clear and refreshing video lectures directly from the author, allowing you to continue learning without any interruptions.
