If you fail your medical.. You obviously need to find out why..
Then if possible go and fix it...
Not exactly sure what the differences are between class 2 and 1..
I don't know why you just didn't go for a class 1 from the start?
The main reasons are.
- Diabetes
- Colour blindness (ATPL)
- Epilepsy..
If you don't have any reason to believe as to why you will fail a medical.. Then you will have nothing to worry about
