Do Ivy league colleges accept students who got some in honor classes?

Yes, Ivy League colleges accept students who have taken some honors classes. While a rigorous course load is important, it's not a requirement that *every* single course be an honors class. Admissions committees look at the whole application, considering the context of the applicant's high school and the rigor of the courses *available* to them. A student who took the most challenging courses available to them at their high school, even if some weren't technically labeled "honors," will be viewed favorably. The focus is on academic excellence and demonstrating a commitment to challenging oneself.
