I was trying to figure out why you would make such a bold statement, therefore I asked where you went to school. I am not trying too figure out who you are, nor do I care. On a side note, I think it's pretty funny that you won't tell me where you went to school, yet you had a picture of yourself as your avatar for the entire world to see. Anyways...
Your statement is absolutely ridiculous. GPA is extremely variable between schools. I went to UCLA for undergrad. UCLA constantly ranks top 3 for sending the most students into medical school. What does this mean? It means that the science courses at the institution are FULL of SMART PRE-MEDS. We did a poll in my neuroanatomy class and out of 250 students, 230 were pre-med! So....not only are these students smart because they are at UCLA, but they are premed, meaning they are ALL trying to get 150% in the class. Then, lets throw in the fact that only 10% of the class will get A's because of the curve that most of the science courses at UCLA have. Your chances for having a stellar GPA are not that high. I once scored a 92% on an o-chem exam (which was super hard) yet because of the curve, I got a B on the exam.
Now lets compare this to a state university. I will compare it to San Diego State because I have talked with friends who go there about their classes. One of my friends I was talking to about biochemistry at UCLA and how hard it was. I worked my butt off and still only got a B. My friend said that her biochem course at SDSU was super basic, and if she had just done the extra credit that they offered, she would have gotten an A+. How is this the same? Me at UCLA knowing a ton about biochemistry/her at SDSU knowing NOTHING about biochemistry, but gets an A. It is not comparable. She has a 3.7 sGPA from SDSU and I am sitting at a 3.4 sGPA from UCLA. Yet, when she took her MCAT, she scored 24 and I scored 31. So looking at sGPA's (which reflect how well you did in your science courses) it seems the 3.7 doesn't really show how well she knows the material.
Yes, you're right. SOME schools may be there same, but saying that ALL COLLEGES ARE THE SAME is not even close to reality.
And your statement about you knowing from personal experience because of your "prestigious" school....prestige doesn't always correlate with academic rigor.
The difference is the competition that you are up against, not the material. The material doesn't change.
