Hi everyone:) I'm 14 and I need your help with my english homework

Can you check this?
Hi Mandy! J
I flew to one week ago. The weather was bad, so flight was belated.
Now it is raining, too. All the time it’s that- rainy, cloudy and
miserably. There’s nothing to do, so I’m studying for hours on end. I came with my parents and we was living in small hotel. Then we was sightseeing . Now I’m sharing my room with two girls – Polish and British.There is really cool. One thing is bad – the weather! There are a lof of polish people, that was nice surprise for me. One girl in my class is Polish! Her name is Karolina. Nice, isn’t it? I feel we will be good friends. In school is one boy… He’s very handsome, we have English together. Daily we have 6-7 hours classes. My educator is really enjoyable and funny. He learn music. I will take up him music lessons. Teachers are usually OK. Apart from math mistress… She is making checks on everyone lesson! On first lesson, either. I think that I won’t have good grade. Our school is bigger than my polish school. There are about 500 students and 50 teachers. My dormitory is very pampered. We have breakfast in 7.00, dinner in 15.00 to 16.00 and supper in 19.00. The food are tasty and there is big choice.What about your grandmather? Is she feeling better?
Sorry, I have to go study math, because we will write check tomorrow.
Kisses from :*
Bye J
