I am an upcoming freshman. I will major in engineering. When applying to the school I chose mechanical because of its "versatility and stability in the job market." (I don't fully understand the meaning of these phrases; I get my knowledge from anecdotal experience when browsing forums). I may want to major in electrical engineering because the math looks more "fun"--calculus fun lol. I am taking an introductory elec. eng. class in coursera vs intro to thermo class in coursera. Right away in elec. I am working with working with taylor series while in thermodynamics it seems very boring "linear" pressure, volume, temperature. (Again, I dont fully understand the courses, because of I only "dipped my toes" in these courses.) I chose this method because I would like to get an easier and less dangerous head start in mofinding the right major for me. Less dangerous in the sense that I'm taking free, non-obligatory intro classes online rather than costly, obligatory (like need A's or else GPA suffers) intros at the university. I am only thinking about mechanical electrical civil and CS. The question is: Is trying (and maybe completing) free online introductory classes a good method of choosing the right engineering major? If I enjoy the intro, I should major and if I don't enjoy the intro then I shouldn't major? Or is this just a bust?
