Two years ago, a GT Admission rep told my DD that they “wouldn’t seriously consider her application without her taking Calculus.” My D had transferred high schools and it prohibited her from taking Calculus her senior year. The GT rep told my DD to figure out a way to take Calculus so that is what my DD did. She look Pre-Cal online over the summer and AP Calculus her senior year. She is now a second year at GT.
I asked GT what they meant by “equivalent” and they said it means regular Calculus, college-level Calculus (through dual-enrollment), basically some form of Calculus. I am sorry to be the bearer of bad news, but AP stats is not the equivalent. To be a viable applicant for GT, the student must have taken Calculus.
