I'm Korean and my English teacher(Korean) said these sentences are wrong.
And I don't get it.
1. Make sure that you study hard every day.
-> She said the whole sentence is wrong.
2. Can I hang out with my friends?
-> She said I must use 'may' when I ask for permission from my parents.
3. Can I play computer games?
-> Same here. (I must use 'may' when I ask for permission from my parents.)
Thanks in advance.
1. Make sure that you study hard every day. -> Seems fine to me.

May is correct, but sounds formal
In everyday English, can is the common word., and is not considered wrong
