I don't remember much about how I felt about various subjects in elementary school.
In high school, though, I felt like I was genuinely interested in pretty much everything I had to or had the option to take.
1. Humanities. I took an introductory course to psychology, sociology, and anthropology. Psychology was definitely my of the three subjects.
Though I personally didn't enjoy the mandatory history course I had to take in high school since it was limited to Canadian history, I enjoy learning about world history. However, I find it challenging to learn about history from any medium since I find the bias injected into historical perspectives detracts from the true value of learning about historical events, major historical figures, etc., especially now that I'm older and would much rather use my own critical thinking skills.
I'm starting to expose myself to the basics of macroeconomics, since I think it's practical information to have a basic understanding of and didn't have the space in my school timetable to take economics as an elective.
2. Sciences. I find all three major branches very interesting. It's fascinating to me that we're able to explain the universe around us and that we're always learning more about it.
For physics, it's funny to me that I once considered not taking it. I ended up taking Grade 11 physics in summer school and Grade 12 physics so that I could apply to undergrad engineering programs. The theories presented in physics were very fascinating, though I struggled the most with the calculations—I think, in part, because I have very poor spatial awareness and struggle to always have full control over my body, especially my limbs.
For chemistry, the stoichiometric calculations were very fun to do. Organic chemistry later caused my grief in university (more on that later).
When I got to university, I realized in my first semester that chemical engineering has very little to do with chemistry. Please don't make the same mistake that I did.
I had to take organic chemistry in my third semester and I literally bombed the midterm exam (got 12% on it). That was the worst grade I had ever received in my life, so I studied really hard for the final exam, participated more in class, and went to my prof during lecture breaks to ask questions. He noticed my improvement, and I'm happy that he had a policy of counting the final exam grade as our overall course grade if students bombed the midterm. I ended the course with a 72%.
For biology, my high school teacher was very focused on the application side, which is probably why I was so interested in it. I'm turned off by rote memorization, so being tested on real understanding of theories and concepts was amazing (and how we should be tested on materials, in my opinion). While I'm not a "health nut," my interest in biology is what eventually got me into learning more about nutrition and fitness on my own.
In university, I had to take biology in my second semester. Our prof was terrible—read off the lecture slides, gave no homework, and didn't provide us with a textbook reference. His final exam was brutal—literally a third of the final exam covered content that he had never taught us. We ended up getting our grades inflated; otherwise, a significant portion of the class would have failed his course.
In my third last semester, I had to take bioprocess engineering. This course was more calculations than theory. It was so boring and the prof couldn't provide explanations for why certain assumption were made, why one formula was used over another in a specific scenario, etc.
Suffice to say, my cohort in university did not have positive experiences with the subject of biology.
3. English. I took AP English Language and Composition in Grade 12, and I absolutely loved it. Rhetorical analysis is such a practical skill to have. Practicing for the AP exam is probably what lead to my ability to read quickly and synthesize my thoughts today, so I'm super grateful to have taken this class.
4. Math. I love solving problems. I think my favourite types of problems to solve were proofs of trigonometric identities. High school AP calculus came pretty intuitively to me, which helped me out greatly when I got to university and had to take Calculus 1.
Calculus 3 in university was rough. When we got to multivariable calculus, it's like my brain decided to stop functioning. I still remember forgetting the left-hand side of Stokes' Theorem for my final exam, which was worth 10% of the exam.
5. Foreign languages. I took French all throughout high school. My French teacher in Grade 9 was so sad that I wasn't able to take his Spanish course starting in Grade 10—I wanted to, but I literally had no more room in my timetable. I'm still friends with him to this day and he still doesn't let me live it down.
6. Music. Like the stereotypical Asian kid, my mom forced me to learn piano at the young age of 4. Later on, I joined choir as an extracurricular in middle school then took vocal class and joined choral ensemble + jazz choir in high school. I really missed being in a music ensemble in university! I don't play piano much anymore, but I still enjoy singing and my S/O likes listening to me sing, hehe.
Nowadays, I have a list of non-fiction topics that I (try to) rotate through while reading—organizational psychology, motivational psychology, product management, professional development, history, technology, systems thinking... Yes, my interests are all over the place.
