You sound pretty burned out already, and you’re a freshman. I doubt this accelerated graduation schedule will exactly help your stress situation.
Of course it matters whether you took Calculus. I get the feeling you’re just grasping at straws here to try to convince yourself that your original plan was optimal - it’s not, believe me. More time is almost always better.
If you got a C+ in Geometry, what makes you think you can handle your soph/junior courseloads? In addition to your “crazy” ECs?
Your “disadvantages of regular graduation” are not very substantive. Not one legitimate reason IMO. </p>
<p>Bottom line: I absolutely cannot see how you can possibly go wrong graduating along with the rest of your classmates. It’s very possible, however, that you will end up regretting graduating early.</p>
