they have to be at a commercial standard from the get-go. the normal flight grading is a partly a test of your capacity to be taught. if you are a commercial pilot, you will be tested on your ability to fly at an expected standard onto which they can mould an airline pilot in a much shorter time frame. therefore the standard is higher. if SW1 did not meet these standards, then grading for the longer course will not be as stringent... a lower standard.
