The tests include an ECG (for the heart), an audio test and an eye test (note: wearing glasses/contact lenses does NOT prevent you from passing this medical. Your eyesight would need to be very poor before it becomes a problem).
For basic questions you can contact us (we are not aviation medical experts) or if your question is of a more complex nature contact your nearest aviation medical examiner.
If you are studying for the Commercial Pilot Licence you will need a Class 1 Aviation Medical. If you are ONLY studying for the Private Pilot Licence then a Class 2 aviation medical is all you need.
