Feasibility of Transfer into Columbia...?

<p>I will take (in September/fall term 2014) :
1- Intro to engineering
2- calc 1
3- gen chem 1 with lab
4- writing course
5- elective which will be economics</p>

<p>Spring term will be (which when I apply to transfer, won't even matter because I wouldn't have started these courses yet)</p>

<p>1- intro to engineering computation
2- calc 2
3- gen chem 2 with lab
4- writing
5- economics course</p>

<p>I have. 90 gpa high school avg,
Fairly weak sat scores/act scores for Ivy League , which I will need to retake to get at least a 2000 sat/32 act
What are my chances? I already took AP calc AB, And AP Chem, which increase the chances of me getting a 3.5+ gpa first semster. </p>

<p>Need some suggestions... And of course I have other schools in mind, but why not try for an ivy, right?</p>
