Medicals - the doctor
I would highly recommend everyone to do some of the medicals at an AVIATION MEDICAL EXAMINER or aviation doctor.
Search it in your mother tongue and you will all find the right person in your country. My country is very small, so only one name comes up on google and he works in the capital. I`m sure that countries, like UK or Australia have several options for you.
You need to pay but they do most of the tests, they are quick and they fill up all the paperwork without questions.
