Hi,
I am a student from Queensland, Australia. Hopefully I can get some help in boosting my english marks in school. There is heaps of great information here!
Hello, Zanitor! Welcome to the gang 
Please, clear up your first two sentences. You say you’re a student then add that you want “to boost your English marks at school”. Are you a schoolboy or a student?
Hello, Zantor, and thanks for dropping a line here! How are things in Down Under?
Hoping you’ll stick around for a while and enjoy your stay.
