It's so confusing cause the email said that DS hasn't met the qualifying standard.
It says that DS was 182 places below the last qualifying rank position for Marling.
How can I start the process for attempting the second test around Easter time, I know others who have done it and still got in.
I think we have all been understanding you as saying that your DS was ranked 182
for Marling - what does the letter say, exactly? If it actually includes the phrase 'failed to meet the required standard', then the advice people are giving you here isn't correct...
If you want to appeal, you have to name Marling on your CAF. If your DS didn't qualify for a place, if will be turned down on the grounds of non-qualification and you will be provided with the information regarding how to appeal. If you don't actually name the school on your CAF, you have not actually applied for a place. At the moment all that gap happened is that your DS's suitability for being considered for admission to the school has been assessed.
