Dear ____ (your friend's name),
How is everything going?
I've just got into sixth form and my life has completely been changed. First of all, my timetable is packed with lessons, from 7:00am until 18:00 in the evening. That is such a long period comparing to my old high school. Moreover, there are a lot of competitions going on amongst us students as this is a particularly prestigious and locally renowned sixth form.Some people easily get jealous over the others who have achieved higher grades than them. This is a bit of nuisance but understandable at the same time, but I guess we just have to （不得不）grow up (成长)and try to get along with each other well (与.和睦相处). Besides,the sixth form I attend now is a boarding school. All the students have their own rooms in the school's dormitory, which means that, from now on （今后）, we should look after ourselves and more importantly, look after （关心）each other as well, in order to prevent any series of （一系列）unfortunate events from happening. To be honest, I think that my sixth form is actually （实际上）a useful environment in which we can build up interpersonal relationships ---- something that we cannot learn just from the school's teaching system. I'll record （记下）what's going on in my sixth form in the form of writing a diary. Think about how interesting it will be to read it after a few years time when I graduate!
Best wishes,
_______ (your name)
