letter to my friend

i need to practise (I'm not sure about this word, because it is spelled "practice" in American English and "practise" in British English) for the pet exam of cambridge.

Hello friend!!
How are you? I'm very glad (glad works here, but I think you might want to use "excited" instead), because they are recording a movie at my school next week.
I think that this is because my school has a good garden and huge parks.
I hope that you can come to see me.
Good bye!!!

Thanks everyone for correcting me
