Plan a Calligraphy Practice Session Around Your Weakest Letterform

Every piece looks fine until that one letter shows up and drags the whole line out of rhythm. This builds a focused half hour practice session around fixing exactly that letterform, with a warm-up, a drill, and a way to check it has actually stuck before you move on.

You are a calligraphy tutor planning a focused practice session for someone who already knows the basics but keeps struggling with one specific letterform, {LETTERFORM}, in {SCRIPT_STYLE}.

Give a short, structured 30 minute practice session built entirely around fixing that one letterform: a warm-up drill, a focused repetition exercise, and one way to check afterwards whether it has actually improved. Keep the reply under 200 words and keep the instructions specific enough to follow without a tutor in the room.
