I'll try my best since my punctuation is only so-so but i'll use a punctuation checker as well as my inferring skills.
okay its all pretty good but there are some grammar errors
"they take no much interest in teaching us" would be better if you wrote "They don't take much interest in teaching us "
"There is a strict discipline about uniform and behavior" would be better as "They are very strict about uniforms and behavior"
"We help each other in studies" This one would be better as "We help each other study"
"Life in the school is interesting and enjoyable" This is just a suggestion since putting that would be fine but i wanted to include this so yeah: "Life in my new school is pretty interesting and i am enjoying myself"
that's really all the errors/ things that could be improved i saw other than those its pretty good to me
i hope i was helpful since i'm not that good at reading cursive...
sorry if i made it worse.
