Urgent!! How many SAT IIs do u have to take??

<p>I have already taken 2 SAT IIs and I am pretty content with the results.
I am contemplating on whether I should take Physics subject test or not (honestly, i really dont wanna take it).
Now that writing is part of SAT I, I did here from some people that colleges only require 2 SATIIs. If I am an applicant applying to one of the top schools such as UPENN, Chicago, etc. how many SAT IIs should I take, or at least required to take?</p>

<p>also, what happens if u do bad on ure ap tests???</p>

<p>im awaiting my results for ap calc and other subjects... i think i did bad on my ap calc (it's AB, which makes it look even worse)...if i knew I was going to screw my ap test, I should've just taken BC
do i have to send my ap scores to colleges that im applying to??</p>
