てから vs 後で: what's the difference?
Both put A before B. てから stresses "first A, then B" and can mean "since"; 後で just says B comes later. With examples and a drill.

The patterns
- てからAfter doing A — first A, then B; since AOpen the lesson
- 後でAfter A (just the order in time); laterOpen the lesson
The difference
Both put A before B. てから attaches to the て-form and stresses the order: B happens only once A is done, often as a necessary first step — 手を洗ってから食べて "wash your hands, then eat". 後で attaches to the た-form or to a noun + の (授業の後で) and simply says B comes after A, without the "first A" emphasis. Only てから can mean "since": 日本に来てから三年になります "it's been three years since I came to Japan". On its own, 後で means "later".
Side by side
て-form + から; た-form + 後で.
"Since" is only てから. A noun takes の後で.
てから: A is a condition for B. 後で: just the order of events.
後で on its own means "later".
