It depends what grade level, I took AP psychology. In my opinion, most of the actual content isn’t too hard to grasp (the only thing I had to really try for was the science based things such as synapses/neurotransmitters etc) but I took it in grade 11 so if you are in grade 12 there’s a chance you may have actually covered some of that stuff already if you took anatomy/biology. The challenging part of psychology is that there is a lot of material (especially for AP) and a lot of the language/terms are going to be new so unless you have prior knowledge you’ll have to make sure to stay on track. However, I really think it depend on your grade level because I have friends who have taken psychology 11/12 and it was no where near as much information as I had. Overall, I’d say that it’s pretty interesting, just a lot of information, and you have to actually understand what you memorize because there are a lot of questions/assignments that require you to apply your knowledge.
If you have any other specific questions I just lmk :)
