In an IB school, I took IB MYP classes in freshman and junior year. In junior and senior year, I take IB DP courses (which are weighted like AP courses). I have not seen a sure answer on how IB MYP classes are weighted by colleges. They are definitely easier than AP courses, but I do not know how much harder they are compared to normal courses.
It really depends on the college. All the colleges weigh the GPAs differently. Some actually take APs and IBs together and weigh them the exact same... (Like UCs). I would advise you to check out their websites or search up "Reddit [college name] IB courses" and get more details
