How can I take the 135-hour CA real estate license course?

You can take the required 135-hours of pre-licensing education online or in-person at a local school.
Most students prefer to take the courses online since it gives them more flexibility and they can typically complete the courses in a shorter time frame.
If you take the courses in-person at a local school, you will have to complete the courses according to the school's pre-set schedule.
Online courses are usually more affordable as well.
