Do you want a two or four year college experience - bcuz I don’t think you can transfer at one year but maybe I’m misreading,
“To be eligible for transfer admission, you must complete a minimum of 60 UC-transferable semester (90 quarter) units by the end of spring term prior to fall admission.”
Ok - you didn’t get rejected by your dream college. You got rejected by a college. There is no dream. All have bad roomies or profs or food or you name it.
You can do everything you want from Riverside. So if you want a four year experience, it’s great.
If you want to save money, go elsewhere and not live the college life, then go CC. That’s fine too.
Good luck.
