I need tips for studying.

I dropped out of school about 8 months ago and haven't studied for a while. I've decided to take the GED, but I don't know where to start. I'm not American, so I don't have any friends to ask about the GED.

I didn't study when I took the GED practice test and I want to improve my score. I especially struggled with social studies and math.

I'd appreciate any tips.
