how do deal with the jealous

I think I feel a lot jealousy, especially when someone does not study hard, yet gets a higher score than me. I get very angry. I know this feeling is not healthy for me, so how can deal with it ?

Stop thinking about what other people do. Put all your energies into making your English better.

Plus, how do you know they didn't study hard? Unless you're monitoring them 24/7, you have no way of knowing. Get over it and you should study harder -- and perhaps you'll get better grades. I hope you do. But you won't get there by just getting angry about other people's study habits, which are absolutely none of your business.

Jealousy is all the fun you think they had.
