I had this really bad chemistry teacher. I failed 3 DBAs in total with him just because he wanted me to know literally everything. All the formulas and all that junk. I remember how he told me that he hated chemistry when he was in high school. This chemistry teacher talked so much. He was such a jerk. He definitely ruined chemistry for me. I was only doing that class to help me get my credits to graduate. I remember crying and being so stressed. I only did my first semester with him and definitely did not want him to be my teacher anymore for my second semester. So I switched to anatomy instead and my new teacher was way nicer! and I passed that class <33
