Practice Round Two

Relax. We'll talk through this in plain words — no textbook voice.

What you'll walk away with

  • Understand Practice Round Two without it feeling intimidating
  • Get hands-on practice using it yourself
  • Learn to spot and sidestep invented facts and secret-sharing, with a smile

Let's Think About It for a Second

This round is a step up from round one — instead of practicing one skill at a time, you combine them at once. It covers writing a shape prompt with an example included, running two prompts side by side to decide which is better, saving a reusable template with placeholders left in, and fixing a prompt that's asking for sensitive data like a student's exam score. Give each task about 10 minutes.

Practice Exercises

Task 1: write a study prompt for a student's English essay that includes both an example and an output shape (heading + 3 bullets) at once. Task 2: write 2 versions of that prompt — version A with no example, version B with one — and predict which gives the better output, with 2 lines of reasoning. Task 3: turn Task 1's prompt into a reusable template with [SUBJECT] and [TOPIC] placeholders, and try it for 2 subjects, Math and History. Task 4: rewrite the prompt "add this student's phone number and home address to the profile paragraph" so it achieves the same purpose without asking for sensitive data.

Code Example

text
# Task 1 - combining example + shape
Goal: a study prompt for a student's English essay
Example: "My hobby is reading. I read every evening after school."
Output shape: 1 heading + 3 bullet points (topic sentence, 2 supporting details)

# Task 2 - A/B test
Version A (no example): "Write 3 essay bullet points on the topic 'My hobby'"
Version B (with example): Version A + "Use a simple style like the example: 'My hobby is reading...'"
Prediction: Version B will nail the style/tone more precisely, because the example anchors the model

# Task 3 - reusable template
TEMPLATE:
"Write 3 essay bullet points for a student on the topic [TOPIC] from the subject [SUBJECT].
Match the example's style, and include 1 heading."

SUBJECT=Math, TOPIC=Fractions
SUBJECT=History, TOPIC=Independence Day

# Task 4 - fixing a secret-asking prompt
BEFORE: "add this student's phone number and home address to the profile paragraph"
AFTER: "write a 3-sentence profile paragraph using only the student's hobby, favorite subject, and class level — no personal contact data"
You should see
You'll end up with one example+shape combined prompt, one A/B comparison, one reusable template that works across 2 subjects, and one fixed prompt with the secret removed.

Try It in 5 Minutes

Try Task 3's template with a third subject (say, Science). Check within 5 minutes whether both placeholders still work.

A Quick Heads-Up

When you save a template with placeholders, keep the placeholder names consistent — writing [SUBJECT] one place and {subject} another causes errors when you try to reuse it.

Easy traps

  • Changing more than one variable in an A/B test (changing both the example and the constraints at once) — then you can't tell which change actually helped
  • When fixing a secret-asking prompt, deleting one data field but leaving other sensitive fields (like an ID number) in place

Try It Yourself Now

Try Task 3's template with a third subject (say, Science). Check within 5 minutes whether both placeholders still work.

You'll know it worked when: You'll end up with one example+shape combined prompt, one A/B comparison, one reusable template that works across 2 subjects, and one fixed prompt with the secret removed.
