How do I ask a TA to Raise a grade nicely?

<p>I think I got my passing grade for effort in religious studies (taking p/f b/c it’s elective), although I’m pretty sure I failed it (below C-), and so did most of the class. But I think this situation is extremely rare. Not just the leniency in the final grade, but also the ridiculous things he wanted us to learn. It was an intro class for crying out loud…</p>
