I was thinking along the lines of a gazelle of some sort for the hipparion and possibly a cheetah for the carnivore, but does anyone have any ideas or good sources with the answers?

So here's the deal. This quarter of college is almost over, and its not very likely that I will pass the chemistry 101 class I'm in. I want to take cellular biology, which Chem is a prerequisite for. Since I'm enrolled in chem right now, I was a able to succesfully register for the cell bio online. Here's my question: If I don't pass Chem, is there any chance that I will be able to stay in the cellular biology because it may not be noticed that I didn't pass?
