2.11 What features were new to you and which were most useful?

While learning about formulas and functions in Excel, I discovered several useful techniques that will make my data analysis tasks more efficient. The use of absolute and relative cell references was particularly valuable, as it helps maintain accuracy when copying formulas across multiple cells.
I also found the Autofill and Insert Function (fx) features extremely helpful for saving time and reducing errors when working with large datasets.
Among the functions, I found COUNT, COUNTA, and AVERAGE immediately applicable to my daily work. Exploring the Formula ribbon also introduced me to new categories like Logical and Text functions, which I plan to use in upcoming reports.
Overall, this module improved my confidence in writing and managing formulas effectively, and I look forward to applying these techniques in real-world Excel projects.
