If I am reading your posts correctly, it seems like your child is in a school, by choice, that just doesn’t offer the STEM experiences you want, because they are trying to work around an athletic schedule. It seems to be that your student is going to have a different application than maybe some STEM applicants, and that’s OK. When we were going through the application process we got the message from many AO’s that they are looking for different. They don’t want to fill up their class with students who all had the same experiences in high school. They appreciated students who showed a passion for an activity rather than one who was clearly just trying to check the boxes with activities they thought the AO’s wanted to see. Showing an aptitude in math and science, through coursework and test grades is helpful, but your child is also showing other strengths and skills through their commitment and success in their sport. I think it’s great that you are looking for some STEM opportunities and maybe something will pan out, but if not, I would recommend your child embrace what makes them interesting in their application. Another option would be to transfer to a more typical school with the activities, classes and experiences you are looking for, but I suspect that means scaling back on the time spent on the athletic activity your child is in, which I suspect is not an option.
I get it…my daughter was in regular high school – but missed a lot of school due to her sport which was not school related. It was hard to get involved with school activities that were flexible enough to allow the absences she needed for competitions and practices. She did find some but it was a balancing act and she could not get as involved in those activities as she would have liked because they were second priority. We did talk about moving to a different school at times that would maybe work better with her sport, but she did not want to give up the “normal” experience. And those school related activities were important to her. She probably sacrificed a little with her sport for that decision but for HER the balance was important. Her school also did not offer as many AP classes as I see others do here on CC and the way they did their scheduling, it was hard to fit a lot in. My D took AP Bio but not AP Chem or Physics. Those she took as honors classes. She did take math through Calc BC and senior year took a Dual Enrollment math class at a local university. I’m not sure if she could do it all over again if she’d make the same course choices, but there isn’t much she could do about the number of AP’s she took.
