I assume your question applies to academics, and I hesitate to answer with a flat-out yes. Like many top-tier schools, very few people fail; the grading curve accommodates most students and professors have open-door office hours to give extra help. However you may believe your peers are smarter and more disciplined than you, I certainly felt like I struggled just to keep my head above the water. I came from an atmosphere where I was one of the top students but at Stanford felt below average. This is a testament to the quality of students Stanford admits and how hard they work while being there.
If you do get the same impressions, my advice is to disregard them. Looking back I absorbed a lot of knowledge even in classes I got bad grades, and after a few years of professional experience noone cares about your GPA.
