In real work

Drill: build a 6-row renewal schedule with EOMONTH without peeking. Subscription renewals in Coimbatore and Paris bill on month-end. Classroom drill: write three brand-new EOMONTH formulas on a blank sheet using names from your own city — if you can invent them without the page open, you own the skill. Then break one formula on purpose and watch the error; recovering from that break is half of interview readiness. Always verify with a known calendar date before trusting a long chain of date formulas. Keep a personal notebook of the one mistake you make most often with this function; review it monthly. When Excel versions differ at home and in class, write the fallback formula under the modern one in a comment cell.
