<p>I already took World history (730), Math Level 1 (770) and Math Level 2 (800).
I am taking the Reasoning test and an AP World History in May. I think to take some subjects in June: Physics (I will get around 680), German (about 650) and WHistory again (aiming at 800). Do you think it is necessary to take more subject tests having in mind that I am an international student with a low GPA of 3.5</p>
<p>Most schools only require 2, but since you are an international, you should look closely at the requirements for internationals of the schools in which you are interested and, if necessary, call them to ask. Some may not require any, some may require many.</p>
<p>Yah I think you should just retake the World History test and try to improve that score after you have taken the AP test. That would give you 2 solid scores in SAT subject tests.</p>
