Hey, so I had a rough first year due to family issues and i had some issues with my courses. I only have 24 units for my first year and I don't think I'll be getting into any of my programs. What happens if I don't get in? Will I just be in an undeclared second year program? Im in social science btw.

You will still be in General Social Science for next year. But whatever major you want to apply in, make sure you take those courses and try to improve your marks to guarantee getting in to some majors. Btw, you can still get into a second year program with just 24 units, just as long as you have the required cumulative average and courses you need for the program of your choice

Shouldn't you know already whether or not you got in? It depends more on your average than the fact that you have 24 units, unless you're missing required units. If you've completed 24, then you should have been reviewed and everything.
