<p>I received PBK as a junior last year with a 3.954. Remember faculty recommendation also plays a role with PBK nomination. I know a couple folks who had GPAs higher than mine but did not get the nod. </p>
<p>In terms of GPA going up and down throughout college, it depends on the student. If you find something you really like and excel at to major in, your GPA will go up. If you flit around taking random intros (which are harder than a fair amount of upper levels) and/or end up pursuing something that is not your strong suit (like staying in engineering when you shouldn’t), your GPA will likely go down. Common sense but true.</p>
