Those are quite interesting. The test for 13 year olds looks pretty easy for 13 year olds; the high school one looks challenging for that cohort and the undergraduate admissions test is harder than any test I was given at that age. To get into MIT in the 80s the only formal test was the SAT plus you wrote a few essays. My high school didn't do "AP" subjects nor compute GPA nor class rank, just ABCF twice a year, and had essentially no electives. So basically they just looked at my SAT scores I guess. I could not have passed that Romanian test at that age.
