Chance for admission

hello. my son always wants to go osu after he went high school.
now he is senior, and will apply on next Monday(10/21or this Friday(10/18) he has 35 at ACT, and 3.67 unweighted, 3.98/4.25 weighted GPA,no rank system, he’s doing science club, orchestra, and korean martial art with black belt, he completed 6 AP(ap scholor with distinction) and now 5 more Ap in senior, his ap courses are calculus ab, bc,physics, biology, chemistry, computer science, world history, american history,government,english literature, environment science,
he volunteered in cleveland clinic and his name will on the paper,
but he doesn’t have any work experiences.
on naviance his school usually applied 75, and accepted 50,only by gpa and act looks so safe, but i don’t know he will be accepted or not, he will be choose biomedical engineering for major and honor program.
i am from South Korea, and he’s born in America and he is my only kid, honestly i have no idea what is going on college application.
will it be get first wave if apply earlier or doesn’t matter apply before 10days or 14 days?
Any reply will be very helpful, thanks for advanced

I think your son’s stats are competitive for tOSU, and Naviance for your school supports that, so he should be fine. If he applied EA, he should hear by late November or mid-December. The honors issue is more of a mystery. It is VERY competitive and the engineering school, I think, is particularly competitive.
