Hi, I'm in the process of putting together my application also so can't help much. In regards to the letter from school, this has been my easiest task so far - just called up school office told them what I needed, they typed up a letter saying I was taught and assessed in English and and years I attended, it was then signed by a teacher who knew me. I picked it up a few days later. May be worth just getting one anyway, better too much info than too little I reckon. Good luck
