All about me my timetable and favourite subject (s)

Му favourite subject is English i like it.My timetable is very very bad!Because i don't understand it.(

Hello, Tom!

Thank you for your letter, it's always great to receive it. In your last letter you told me about your school and asked me some questions. 

I had to change schools and it wasn't such as easy as anyone might think, it was hard to me to communicate with my new classmates, but later I get along with them.

Firstly, it seemed really unsolvable for me to make friends, but now I have a lot of friends from different classes at our school. 

I think that school uniform is very useful, because it prepares us for our future. At work we must wear an official uniform and we won't have any choice.

Sorry, but I must finish now. I have a lot of work to do.
Hope to hear from you soon,

Пока что вот это, но скорее всего я что-нибудь ещё допишу:
The joke - тут конкретная смешная история имеется ввиду, полагаю артикль должен быть определённый
просто received без have
в этом же предложении концовку лучше "a telegram which started with a notification about Pat's mother's illness" или чья там мама заболела я понять не могу
but for that he needed priest's help тут местами поменять: but he needed priest's help for that
if Pam wanted to say any more. слово any лишнее
and a bad handwritng. - артикль "a" здесь не нужен
