I thought chemistry was cakesauce compared to my engineering classes. But then again I only needed general chemistry I don't like chemistry though because to me it feels like memorization, memorization, memorization. I rather learn the concepts and solve problems, not memorize formulas and random facts. For example, most of my upper level engineering exams and finals were open book/notes.

Physics is the the most underappreciated( as in your job options are super limited ) but the hardest degree ever to get. I took a ton of extra physics classes outside of my major and they were SUPER hard but the most rewarding.
