Excel Essentials! Complete Mastery of Must-Know Functions

🙋‍♀ You've probably had thoughts like this, right?

"Functions! I understand them when I hear about them, but when I actually try to use them, I can't think of them…"
"How great would it be if they just came to mind at the right moment?"

"You know it's good to learn Excel functions, but when you actually try to use them, your mind goes blank and you feel lost about which ones to use - I'm sure everyone has had this experience at least once, right?

Excel isn't difficult up to the basic stages of entering data and applying formatting. However, what really saves time and increases efficiency is 'functions'.

Functions are very reliable tools that calculate and organize things for me, but many people give up because the rules seem confusing or too numerous.

This course is an essential class for those people.

It doesn't simply list how to use functions.

"Why it should be written this way", "Which function would be good to choose in this situation"

I've structured it with step-by-step explanations so that anyone can easily understand.

Additionally, this isn't just a lecture you listen to and forget, but is designed so you can learn by following along with practical examples after listening to the lectures, and make it 'your own' by solving given missions. It's structured as a challenge course where you can fill in your weak areas through Teacher Eunhee's professional feedback.

The 'Must-Know Functions Complete Mastery' challenge course consists of the following stages

1. Learning functions while taking online classes and

2. Complete and submit missions for each function

3. You can accurately understand and use functions while receiving professional feedback.

How to complete missions

Function-specific missions are prepared below the last lecture for each function
Read the mission description, download the mission attachment file, solve it according to the instructions, and submit it

By the time the challenge course comes to an end, functions that once felt vague will naturally become familiar,
and you'll be able to use them on your own when needed in real-world situations.
