You shouldn’t really be all that scared for the A+ exam. It is entry-level for the industry; not designed to be hard, just weed out some of those who aren’t very knowledgeable. I’m not sure I understand the question, though. Are you looking for places to study/courses in San Diego, CA? That’s how I understand it.

I took my test at New Horizons (http://www.newhorizons.com/content/index.aspx) in Dublin, OH. They’re international and they may have one near you. I know they also do coursework and they do show the A+ under their ‘Courses’ section so I would check that out.
