Your stats put you in the upper quartile, you’ll have no problem with grades at A&M.
A&M isn’t known to have difficult engineering college. They accept around 85% of applicants. And many aren’t qualified to be in engineering so they don’t do well.
For example, I have a friend whose 2 sons got into A&M college station engineering, both were solid “C” students at a rural Texas public HS, after 2 semesters at A&M they were in different non engineering majors. They shouldn’t have been in engineering in the first place.
A&M engineering admission stats:

10k applied, 85% offered, 4000 enrolled as freshmen. ~2000 will graduate with an engineering degree. So around half fail out.
