When I was in the Army, I learned Excel on my own! I had created "master trackers" for the unit, First Sergeant, and the Unit Commander! These trackers, I had created, had auto calculations built right into the excel tracker. I had created many of these ON MY OWN with NO PRIOR EXPERIENCE nor ANYONE teaching me how to do these programs into Excel. Now, it's great seeing someone on here teaching others how to use the Excel program. It's fun and, once you learn how to do these programs, they can be of MUCH value and benefit to ANY business that need "trackers".
