Converting IB scores to GPA

<p>I don't like in America so I don't really understand GPAs. So anything above a 90% is 4.0 right?
What IB score out of 45 is a 4.0?</p>

<p>I’m not sure, but there is an old thread asking the same question. There didn’t seem to be a definitive answer. <a href=“http://talk.collegeconfidential.com/high-school-life/56588-ib-grade-conversion.html[/url]”>http://talk.collegeconfidential.com/high-school-life/56588-ib-grade-conversion.html&lt;/a&gt;&lt;/p&gt;
