Just to share my experience during my visa process. I know a lot of people who shared their experiences have helped me a lot.
My medical at SLEC was great and did it for 2 days. First day, i went through physical exam and vaccines. I got there at before 6am and number is already 50 in line. But all is good when i got the result the next day. They stamped "N" on my passport. Not sure what it means but i assume it was normal then.
