'Hope' is what you would LIKE to happen.
'Expect' is what you think will PROBABLY happen.
If you are taking an exam, you might say:
'I hope I get an A grade. But I didn't work very hard, so, realistically, I expect I'll only get a B.'
By the way, please don't write 'wanna', especially if you are asking strangers to help you. Native English speakers don't use this form in everyday writing. If you browse through the pages of this site, you will see that it is only learners of English who write like this. If a native English speaker wants someone to help them, we would say politely 'I'd like to know..' We would never write 'I wanna' in a request for help. It looks rude and childish.
