<p>In our school, ib is considered as a more advanced system than AP
Only Top 10% student are allowed to take IB classes</p>
<p>But I heard that AP is more useful if you want to study in US
Is that the case?
Will taking IB classes become a disadvantage?( IB is harder and students might get lower GPA, I heard there are students dropped out every year )</p>
<p>I am a sophomore.</p>
