Well first thing you can do is :
1. Get the CAA medical email address.
2. Find a musical track.
3. Make a video of you getting in and out of the airplane,whilst dancing to the music.
4.Email it to the CAA and ask them you are ready for a medical flight test and would like to arrange one. They should get back to you in 3 days or they might just cancel the whole thing. they are bureaucrats not human beings remember.
Good Luck
PS:Just get your NPPL for now and save the aggravation.
