General Ed courses are what you need to take in college that will count towards credits in earning your overall college degree. Prereqs are courses that you have to take before being able to enroll in another course. For instance, let's say nursing requires Chem 101 but the prereq for that may be Chem 51, which means you have to take Chem 51 BEFORE you can enroll in Chem 101.
You should go online and look up CSULB, Fullerton and Dominquez Hills prereq requirements for their nursing programs
first, print them out and compare each program, then meet with a college counselor at El camino college and let them know your intention to transfer in a year or two and have nursing be your major. That way, they can make sure you are not only taking care of your general ed requirements but also your nursing prereqs. All RN programs have prereqs typically 3-4 upper science courses with a lab (anatomy & Physiology, microbiology, chem etc) a math (statistics or algebra), an english. But it can vary slightly each school, so make sure you look over each nursing programs prereqs carefully before making a decision on which nursing program(s) you want to apply to. Some nursing schools only have 5-6 prereqs, others have more. I've been trying to stick with 2-3 nursing program choices that have close to the same prereq requirements, so I won't be taking prereqs forever.
HTH! If you have anymore questions just ask!
