First of all, there are millions of high school students graduating, and very few vloggers - they are not even close to representing what 95% of high school students are doing.
Second of all, there is nobody out there providing fact checks for the Vlogs. You can make one yourself and say whatever you want.
Third, the average GPA of graduating high school students is around 3.0, so you are ahead of the curve.
Finally, don’t focus on what other students are maybe doing or not doing. Decide what you want to do, and go for it. Focus on doing your best, and on finding your own path.
@rexbert12 is right - instead of watching some annoying teenager blab on about all the things they are doing, spend your time doing something like studying or engaging in whatever extracurricular activity interests you.
