@WTXMama Your prospective student center rep is confused what you are asking or is ignorant of the rule for dual credit vs AP credit. The guidelines are changing every year, so unless a rep is actively keeping up, they can give old info. My son is a current Jr Engineering major.
Here is where the distinction lies. A&M does not want students to take credit for Calculus 1 and 2. They want them to take it in a college setting, which is much more in depth than a high school AP class. Dual Credit are college credit classes. Colleges do not want you repeating courses that had a passing grade. So, your son would not repeat Cal I and/or II, but take additional math classes to satisfy the ETAM requirement.
Students who take college courses through their local community college that will also count toward their high school diploma are dual credit classes. Students must submit official transcripts from the community college or university that offered the dual credit classes to the Office of Undergraduate Admissions to receive transfer credit.
Students must complete the following courses in at least two semesters before applying to an engineering major: two engineering courses, two math courses, and two science courses in the first year engineering curriculum. Exceptions will be made as needed for students entering with credit for the required courses. https://catalog.tamu.edu/undergraduate/engineering/
Required Coursework - General engineering students are required to complete at least the following courses ON CAMPUS at Texas A&M University with a minimum grade of C or higher:
Engineering: Two engineering courses from the following list:
ENGR 102
ENGR 216 or PHYS 216
Science: Two science courses from the following list – PHYS 206, PHYS 207, PHYS 222, CHEM 107/117 or CHEM 101/111, CHEM 102/112.
Math: Two math courses from the following list – MATH 151, 152, 251, 253, 304, 308; CSCE 222 (Discrete Math)

If a student comes in with credit for Math 151 and/or 152, they will be required to take two additional math classes from the above list, on campus, at A&M, during their freshman year.
Only the above sciences will count for the engineering degree. If a student comes in with credit for one or two sciences, they will be required to take additional science classes from the above list, on campus, at A&M during freshman year.
