Academic Integrity Tips

Using AI tools responsibly:

3. Not checking AI citations - ChatGPT makes up fake references
4. Using only one AI tool - different tools excel at different tasks
5. Paying for Pro plans too early - free plans cover most student needs
6. Letting AI do all the thinking - you learn by struggling, not skipping
