Need Help for Transfer!

<p>Hi, I am a high school senior and I didnt get into any of my dream schools, and I had a very bad experience with a college coach which i do not want to get into great detail about. So i am here to ask about the transfer process. I know I want to transfer into either Cornell AEM, or NYU Stern, and want to know a couple things.
1. Does it matter which college I go to first year, I am considering either Drexel (which also would be good to know if it will be too hard to transfer credits) , Drew u, or Sacred Heart
2. Should I retake the SAT and ACT, super scored my SAT was about 1800, and ACT 25
3. Should I do anything this summer to boost my chances
This whole college experience was and is a total nightmare for me, and i wish i could start over because i had no help from my guidance consular who didnt even place me in the classes i want because she thought i was too busy, and was screwed by a coach that i "knew" was going to get me in.... any help will be great and is really appreciated!</p>
