I think the best thing is to ignore & forgive them concentrate on your study & try to maintain your position.
The people who do like this they cannot work hard but only wish to come first.
If you keep yourself upset with such thoughts you will lose your position.
They really want this.
Do not let them succeed.
After a few years all of you be away & then miss school life.
Pray 5 times &read Quran daily with translation.
Pray for yourself that Allah save you from all jealousy.
