Only if you get the top score and add 10 to it. No valid IQ test can be given in 30 minutes, so I would be very suspect. The highest score on the so called "Novis Mental Ability Test," is 155. Many who have scored "off the scale" of a regular IQ test would test "low" on the Scientology created "Novis Mental Ability Test". It is not even accepted for membership in any of the High IQ Societies (such as MENSA or The HI Q Society).
Normally online tests are accurate, but in order to test your psychic ability you should look elsewhere. Online psychic tests aren't going to have the accuracy you need and you should go see a professional to test your abilities.
Aston Index is an ability test.

Reliable indicates that each time the experiment is conducted, the same results are obtained (accuracy). Valid indicates the experiment (or test) has controlled variables and used an appropriate method/model.
No. Just show them your prescription with the prescribing doctors name, and there will be no problem. That is unless that medication will affect your ability to perform your work duties.
