Don't worry, the employer won't go to the school to investigate your resume. You should pay attention to these points.
First, the award: nonsense. If there is really nothing to win, think about what clubs there are in the school, make up a speech contest for what clubs and competitions, and get yourself an award.
Second, the school position, nonsense. There are so many clubs anyway. If you find someone who knows you better, say that you have been a cadre.
Third, work experience, nonsense. See what position you want to apply for, think about what skills this position needs, think about what jobs can be linked to these abilities, and then find a place you are familiar with. Of course, don't say anything famous, just say that they can't find it in several corners.
Then be calm during the interview, as if those things really happened.
I can't help it if I make up knowledge. I study management, and I don't know much about your high technology. Sorry, I can't help you.
