To be able to enroll in college you must have either a high school diploma or even a GED.
Without either the high school diploma or GED the college will usually deny you acceptance into the college.
Getting a GED is very doable if you're willing to study and take the test to get the GED and having a GED today is very important to get into college or find a Job.
Without the GED or high school diploma it will also be very hard for you to find a job since most if not all Jobs require the high school diploma or GED to get hired.
