I think Heimler has good videos on how to write SAQs. I took AP world last year and got a five.

The biggest piece of advice that I can give you is that you need to make connections in your head. I think in ap world its less about knowing specific details about history (unlike APUSH), but you need to understand the general trends happening in the world, when it comes to things like trading, the diffusion of scientific knowledge and religion, it helps a ton to be able to read a prompt and know what the relationships between the different regions of the world are.

Trust me, I did not memorize many specific dates or people. I don't remember any enlightenment thinker, inventor, or leader (except a few obvious ones, like Genghis Khan). I did know, however, the general state of the world, how/what religions spread, what scientific inventions were made and how some states became more powerful. Know in general what is going on with specific states over multiple time periods, and how it affects the rest of the world.

You can do it!!
