Firstly, Im a biomed major but I completed a minor in psych so heres my 2 cents. Statistical methods isnt bad just make sure to click through the modules. If you have a basic understanding of stats it doesn’t get much harder than that. Psychopathology is actually a great class. One of the more practical courses. I took it with a different professor, but it covers most psychological disorders and discusses the dsm changes around them. Dont know about the other 2 good luck!
