I spent three hours working out difficult physics questions regarding light and its' various transformations and refractions, only to learn one critical part of an equation is slightly off, which required another hour of work to correct.
I loved physics. I took an advanced course in my Sr. Year of Highschool. It was hard at times because I skipped Geometry and Trig, so I had to crash those in as well. but on the whole, I enjoyed it because FINALLY all that stupid algebra was used for something.
Of course, all that brainpower gained is gone. Don't use it you loose it.
I enjoyed Physics, for what it's worth. Unfortunately, I absolutely hate complex math, so it didn't bode well for me. I failed more than one test in that course... :D
Fascinating stuff to learn, though. We did some pretty cool labs... I wouldn't kept it, despite my troubles with the math, but it didn't fit into my grade twelve schedule.
Probably for the best, since I dropped math 12 too. :D
