Two Days Before

• Do a light review of your weakest domain — don't cram new material
• Review your flashcard deck one final time
• Set up your ProctorU environment (quiet room, clear desk, webcam, stable internet)
• Test your computer and internet connection with ProctorU's system check

The Night Before

• Stop studying by early evening — no late-night cramming
• Prepare your ID and any allowed materials
• Get 7-8 hours of sleep
• Avoid alcohol and heavy meals

Morning Of

• Eat a balanced breakfast with protein and complex carbs
• Avoid excessive caffeine — it can increase anxiety
• Log in 15 minutes early to get settled
• Take 3 slow, deep breaths before starting
• Remember: you've prepared for this. Trust your training.

Test anxiety is normal and manageable. Here are evidence-based techniques:

• Box breathing: Inhale 4 seconds → hold 4 seconds → exhale 4 seconds → hold 4 seconds. Repeat 3-4 times.
• 5-4-3-2-1 grounding: Name 5 things you see, 4 you feel, 3 you hear, 2 you smell, 1 you taste.
• Positive self-talk: Replace "I don't know this" with "I've studied this and I'll do my best."
• Progress reframe: If you hit a hard question, remind yourself of the ones you've already answered confidently.
