Is that AP Calculus AB or BC? Are you a high school junior or senior this year? What was your class rank at your former school?
(if your a senior) I would say you have a fair chance depending on when you turned your application. (if your a junior) if your class rank was top 25%, you retook the SAT and get a 600 on your Critical reading you would get automatic admissions and only need to worry about getting into your major.
Because Freshman year you and all other engineering students will share the same major until you take 2 engineering, math, and science classes. Then you will have to compete to transfer into your major of choice based on the GPA you have from those classes. You can get into your major easier by passing the AP test for English Lang which will give you more time to study during your freshman year.
Here is the degree plan.
