<p>I asked about this in another thread.</p>
<p>From my observation, some very competitive high schools (with API better than 900, I only checked 4) have around 10% of students admitted to UC Berkeley, while high schools with API below 800 may only have less than 2%. All these schools are within 20 miles of where I live. To put things in perspective, straight A students that fall outside of the top 2% from lesser API schools are still getting 5 on Calculus BC AP test.</p>
<p>I don’t know how useful API score is. I use it as a reference point.</p>
