1. Is a high school honor student a student in a highschool who gets exceptioanlly good grades?
2. Four out of five of these honor students admitted to cheating.
--- Does "cheating" here refer to cribbing? Because I know that you can also "cheat on sb" for example your girlfriend etc.
An honor student is one who gets good grades, yes.
There are a number of ways you can cheat. You can steal the test from the teacher's files before it's given so you know the questions. You can bring in a crib sheet. You can hack into the school's computer system and change your grade. You can text your friend for the answer to a question that is elluding you. You can simply look at the test of the student next to you.
