As a high school teacher, I can tell you that students will pass their high school classes if they put in the effort to do the work.
This will not necessarily prepare them for college, especially for a difficult university like TU. I've had good students come back and tell me how tough it was to adjust to TU.
When I was a student at TU, getting good grades was really difficult. I took classes at other schools as well, and my A work at those schools would have been B work in most of my TU classes.
I am very impressed that Ramadi has hung in there after two years of disappointment. I will especially be glad to see him back on the field this fall.
I've seen students have trouble making it at TU, then they mature and come back as teachers and great examples for their students.
