Admission into Engineering majors

If I got rejected to the college of Engineering at UT with the major of Architectural Engineering for the Fall 2015 due to the college readiness requirements (have not taken Calculus). Can I apply again after taking the Calculus college class in Summer before starting the Fall 2015 semester? or declare my major as undeclared the first semester and then do the Internal Transfer for the Spring 2016?

Also, since I already have my associate’s degree, I am practically done with basic courses. Can I take engineering courses before I transfer to my engineering major?

Thank you in advance!
