7. Common Mistakes to Avoid When Using ChatGPT

7.1 Giving Vague Instructions

One common mistake is asking ChatGPT very general questions like:
❌ “Explain science.”
Instead, be specific:
✅ “Explain how photosynthesis works in simple steps for beginners.”

Tip: The clearer your question, the better and faster ChatGPT can help.

7.2 Overloading with Too Much Information at Once

Avoid giving too many instructions or long texts in one message. This can confuse ChatGPT or give messy results.
✅ Break your tasks into smaller steps:

• First, summarize your notes
• Then, make a study guide
• Finally, create practice questions

7.3 Ignoring Follow-up or Clarifications

Another mistake is not refining the response. ChatGPT works best if you guide it step by step:

• “Make this shorter”
• “Add examples”
• “Explain in simple words”

Tip: Treat ChatGPT like a helper—you can improve the output by asking follow-up questions.
