Math for sure!
P.E and mathematics
Without question the most difficult subject at my high school was English. People who went on to become authors, lawyers , judges in the higher courts and screenwriters would get low C's and D's. You could complete the class write all your papers and still fail. This
was in the late 1970's and was arguable the best English program in the nation. I had to stay 5 years because I failed English twice my Freshman year....it was hell. It got better in the later years.
Like maybe all of them.
American Literature, I like reading but I am extremely book picky, can't read a book if it doesn't grab my attention by the first chapter. Honestly I haven't read any of the "American Classics" because they bore me.
Math. I absolutely DESPISED math. And about 3/4s of everything I learned throughout my school year as far as math goes, I haven't used once for the rest of my life. Trigonometry? What purpose does it serve in the average life?
English for sure
Mathematics( too difficult for this grey matter) , and business economics ( boring )
accounting is one of my favourite lol but I really hated chemistry at the pre high school level
