Which AP/IB credit should I use?

<p>I'm going to be going CIT in the fall, majoring in either MechE, or, if I can transfer in, ECE. I was debating which of the following credits I should be using and how it will help me:</p>

<p>AP Chem, APCS A, AP Calc BC, AP Biology (5's), IB Physics HL (7)</p>

<p>I know that CIT offers credits for all of these, but should I retake these classes anyways? I am taking BC Calc and Bio this year but I'm fairly sure I'm going to get 5's on them, and while I pretty much aced the other 3 tests, but I took CS in freshman year and Chem/Physics HL last year, so should I be retaking those? Also specifically in regards to using the APCS A credit, I know it covers the 15-112 Fundamentals to Programming class, but I know this is a required class for declaring the ECE major, so if I cover that using my AP credit, then will I be at a disadvantage when declaring ECE?</p>

<p>Thanks for the help</p>

<p>Bump, still looking for some help, especially regarding whether I should retake the intro CS or engineering physics course.</p>
