when i got my visa to VFS long ago,i chat with the staff there,and talk about student visa,she told me that BRITISH EMBASSY order to VFS that don't accept more than 10 applicants student visa in one day,because the British Embassy says,there are more than 5000 applicants already pending at the embassy
And i met one old woman about 45 years old,(in a casual wear,doesn't even look presentable )i ask her what visa you're applying for? and she said "student visa"....

and i conclude....i know whats going on
