The character in a word
A lone character is hard to remember: memory holds on to meaning, and a letter has none. The word it stands in provides that anchor.

The character in the “a familiar look — a different sound” group
The main difficulty of Greek. The letter is recognized at first glance but sounds different: β is a v, η and υ are ee, ω is an o, χ is a kh. A word read the way it looks, math-class style, a native speaker will not recognize.

How to remember this character
A single letter is the hardest thing to remember: memory has nothing to hold on to — a character has no meaning. A three-step loop works: see the character, try to recall the sound (for «omega» it is “o as in "pot", written ω”, as in the word “ώρα”), see the right answer.
And come back to it the next day, not in an hour: a check a day or two later beats a check the same day. Nobody holds the whole alphabet — 37 letters — at once.

The second spelling of the o sound. Telling them apart by ear is neither needed nor possible — the spelling is memorized: ώρα (an hour) through ω, όνομα (a name) through ο.
