Wow, you have a lot of expectations for yourself. I highly recommend trying out a few different courses just to see how they each feel to you. You never know, you might find something you're really interested in and passionate about. I recommend trying introduction to psychology because it covers a lot of different psychology topics to give you a little taste of each (I am biased because psychology was my major and I'm studying to be a therapist). Since you're thinking about police foundations, you should consider looking into a forensic psychology class. Also, since you're not sure exactly what you want as a career yet, try to relieve the pressure to have it all figured out by not expecting to excel at the course. Try looking at the class as a "trial run" just to get a feel. If you put too much pressure on yourself to do well in the class, you risk overlooking the positive parts and it could turn into a bad experience. Overall, have fun with it. Try out an introductory class that you never would consider just to make sure it's not the right fit (political science or biology). As I said, you never know what you will find. Good luck!
