Here's the check list for last-minute reminder:

1. Your Passport:  it's recommended to bring other IDs in case the test center requires two IDs for comparison.
2. No smart watch, only traditional watch:  a watch is not necessary as it shows time on the screen.
3. Make sure your calculator is permitted (ACT Calculator Policy)

If you are aiming at the test in September, don't forget to join our summer ACT course for better preparation.

And also some tips from TrinityScholar

• Wear something comfortable, and bring a jacket for test centers with strong A/C
• Visit the test center in advance if you've never been there.
• Arrive the center 15-30 minutes earlier.
• Bring some refreshment and water, standing by outside the test room.
•  Don't hesitate to raise your hand if there's any issue during the test.

And, last but not least, GOOD LUCK to you all.
