Don’t drive 50 minutes to SMC. Mt. Sac is 50 minutes away as well? Both are ~50 minutes away from you? I looked it up, and Mt. Sac is only 7 miles away.
I’d say take your classes at Citrus, and take the extra class at Mt. SAC if it’s available/convenient for you. Don’t worry about the stats course - many transfers have to take some extra courses after they transfer anyway, so the difference of one class isn’t too big of a deal. Either take that at UCLA, or take a stats course at your CC and petition for it to be articulated. I can’t really tell you anything about that process, because I don’t know anything about it.
They don’t hold it against you if your college doesn’t have the required courses. You can always take the class(es) at UCLA the summer before your junior year, if desired, such that you will be able to completely focus on upper division courses in your junior year. It’s not that big of a deal, though. You’ll have 6 quarters to complete 11 courses (or 12 if you don’t take the class at Mt. SAC), not counting summer sessions - it won’t really be difficult to do.
