I suggest that you learn Excel from scratch using a simple but very effective learning technique. In just a few days, you can prepare for an interview for your dream job. Based on this methodology, an electronic textbook has been compiled, enclosed in pdf format, which in a few hours may be on the desktop of your computer. After 1 hour of study, you will look at Excel with completely different eyes. Everything will become simple and understandable for you. A week later, you can do the work of an office employee of any prestigious company.
