Every MPADQ quiz attempt is gated by a unique access key — a 10-character alphanumeric code that is tied to your license in the database. Your key is generated when you purchase access to the questionnaire, delivered to you with your copy of Take Charge of Your Performance Anxiety, and validated each time you visit the homepage. Understanding how keys work will help you avoid common pitfalls and make the most of your one quiz attempt.Documentation Index

Where Your Key Comes From
Keys are issued through two channels depending on the format of Take Charge of Your Performance Anxiety you purchased:- Print edition: Your key is printed on an insert found inside your physical copy of the book.
- Ebook or audiobook edition: Your key is emailed to you automatically after your PayPal purchase is confirmed. Check your inbox (and spam folder) for an email from Einerlei Publishing with the subject line “Einerlei Publishing: License Key”.
Key Format
Your key is exactly 10 characters long and is drawn from uppercase letters (A–Z), lowercase letters (a–z), and digits (0–9). A valid key looks like:How Keys Are Stored
Behind the scenes, the MPADQ stores keys in aLicense table in MySQL. Each row holds:
| Column | Type | Description |
|---|---|---|
id | INT UNSIGNED | Auto-incremented unique identifier for this license |
licenseKey | VARCHAR(255) | MD5 hash of the original 10-character key |
active | BOOL | 1 (true) when unused; 0 (false) after quiz completion |
Entering Your Key
Go to the homepage
Navigate to performanceanxietyquestionnaire.com. You will see a text field and a Start Quiz button.
Type your key
Enter your 10-character key exactly as it appears on your book insert or in your email. The field is case-sensitive, so double-check for any capital or lowercase differences.
Click 'Start Quiz'
Submit the form. The server will look up your key in the database and route you based on the result.
Outcomes After Submission
When you submit your key,keySubmit.php performs two checks in order — existence and activity — and routes you to one of three outcomes accordingly:
| Outcome | What Happened | Where You Land |
|---|---|---|
| ✅ Valid and active | Key found in database; active = true | Redirected to /start/ to begin the quiz |
| 🔁 Valid but inactive | Key found; active = false (quiz already submitted) | Redirected to /finish/ to view your existing results |
| ❌ Invalid | Key not found in database | Returned to homepage with an error message |
Invalid key. Please follow the link below to purchase a key to the questionnnaire.If you see this message, verify that you typed the key correctly, paying attention to case and any characters that look similar (e.g.,
0 vs O, 1 vs l).
Each key unlocks exactly one quiz attempt. Once you click the final submit button at the end of the Likert section, your key’s
active flag is set to false in the database. You cannot retake the quiz with the same key — but you can re-enter it at any time to return to your results.Purchasing a Key
