Ah, chemistry. I enjoyed chemistry in high school, because the courses I took had a lot more emphasis on theory and understanding than the chemistry courses I didn't take - there was a heavy focus on organic chemistry, and calculations were sparse. So far in university, I've taken the pre-requisite first year (basic) chemistry courses, and second level organic chemistry and physical chemistry.
First year chemistry was...easy, but drop-dead boring. The only thing that made the class interesting was my professor, who was snarky, awesome, and most likely INTJ.
My first semester of organic chemistry wasn't so fun, because it was just a bunch of rote memorization of the different classes of compounds...it was quite boring. The next semester was a lot better, though, because there was more of an emphasis on 'puzzle-solving'; a lot of the time, questions were "how do you synthesize compound B from compound A?", and there were multiple ways of accomplishing it. I really enjoyed how a lot of the times, the compounds would appear to be totally different from, say, an example in the book/class, but still be the same
in principle.
Physical chemistry was also pretty great. I really enjoyed taking the tests, because every problem presented always had a solution that you had to find through formula manipulation/algebra...I saw it as putting together the pieces of the puzzle. Professor was kind of dry, though

.
The thing that really gets me about chemistry is the labs/lab write-ups. Sadly, I am terrible at working in chemistry labs, and am always disorganized/slow/unsure of my measurements. Definitely not my strong suit...
