Remember that if you take social science courses that will require thesis, database exploration and usage, and writing intensive assignments throughout the course, this can take a large chunk out of your time.
Since you are working as you are, I stand by my suggestion to at least hold off on A&P and sociology. OTOH, if you get some really easy going profs for soc/psych, you might be fine w/ back-to-back social sciences; but the A&P is time-consuming in it's own right as well.
Anyone that hints or outrightly states that their course will be writing intensive in their course description or syllabus is telling you a very large percentage of your grade will depend on writing intensive work with very structured rubrics, and yes, to meet those strict requirements can be time-consuming. So, if you dislike making theses and exploring data bases for research-based, scholarly work to support your own work, and if you dislike them being sticklers with format requirements, the work for their courses may take you longer and a bit more sweat to get the A.
I will say if you take soc and psych at a community college, you may not get instructors/professors that are so demanding in this regard, but it really depends upon the professor and the department pedagogy. So, if you want to take these courses, try to find out what type and level of demand you will have to meet to do A work.
