It sounds like most of us would qualify under section 1:
Section 1 applies to people who already speak good English, and who have an educational qualification which could only have been obtained by someone who has good English
"If you have an educational qualification which could only have been obtained by someone who speaks good English, we will accept this as proving that you meet the standard for naturalisation. This qualification might be, for instance, a GCSE or A level certificate or a degree or diploma from a University or Higher Education Institution, either in Britain or another English speaking country. We will also accept degrees or diplomas from Higher Education Institutions in non-English speaking countries where English is the language of instruction, provided that you send us a copy of documentation which proves that the course is conducted in English. "
So what would be the benefit of waiting until "Section 5" is introduced?
