What are your goals? A high-paying job, as quickly as possible, to help support your family? Then take a look at two year certifications that the community college offers in fields like healthcare, and plan for childcare so that you’re available for the full day of school that those healthcare certifications will require. Fulfillment of an educational dream or career dream? A first class or two toward the desired degree. Intellectual stimulation? A chance to get out of the house one night a week without the child, and just have 3 hours in the classroom that are all for you, learning together with others in person for self-fulfillment? Then a first class or two in fun subjects with a great teacher. Just a bachelor’s degree in something, so that you have set an example of educational achievement for your kids someday? Then, especially if you’re pregnant, identify CLEP exams that are accepted at your local community college, with a transfer agreement to your local state 4 yr college, and look at the website Modernstates.org for online lectures and vouchers for free CLEP exams, to start working towards the gen eds for the degree.
Definitely no more than two classes a semester, and I’d say even start with just one, unless the fin aid needs dictate that you take two. Depending upon how sick you get with pregnancy, you might be able to start this summer with one to two classes, and then take a break for fall semester, what with the newborn in the fall.
