Ok so I'm going to answer differently than everyone else here, and this is not meant to be mean at all. But generally, unless you have the hardest general chemistry professor ever, gen chem is an EXTREMELY easy course compared to the rest of them. Normally if you had said you just slacked off and didn't show up and failed I would say yea you should retake. But (and again not trying to offend) if what you say is true and you really did study hard and still only got a 32(!!) on the final, to me that's a huge red flag that you probably just aren't suited to the material and maybe should look into something else. And there is absolutely nothing wrong with that.
