Perspectives of Science and Engineering Grading

<p>To any Yale student formerly in PSE, how is Perspectives of Science and Engineering graded? Is it on a Pass/Fail basis or an A/B/C/D/F grading system. Also, if its graded by letters, what kinds of assignments are there, and does everyone get an A? </p>

<p>I don't want to overwhelm myself with an extra course my first semester at Yale, so if anyone can give me information of the grading that'd be great.</p>

<p>Could anyone from PSE shed some light onto this?</p>
