Soooo, I am aware that I am colour blind. I have tried the ishihara test, and..... no chance. I believe worst case I will be CP4, as I can confidently differentiate the colours on the trade test. When I come to apply for the RM, is there any way I could bring this up (Given I pass everything else), which might speed up the application process, instead of unnecessarily going through the ishihara test etc?
