Uh.......let's see.
I think it was 8th grade for me.
12th Calc
11th Trig
10th Geometry
9th Alg II
Yeah, that would have been 8th grade then for the official start of Algebra.
I think it coincided with the introduction of negative numbers, which was rather odd at first, as was the use of letters in place of numbers.
Luckily I took to the process rather easily.
I was in the "gifted" program / advanced classes from mid-elementary till graduation from high school and I believe we started formally learning algebra in the 7th grade. Not sure about mainstream.
Similar here. Our "gifted" program struck me as just a way of taking some kids out and babysitting them elsewhere for awhile. Most of the stuff we did was rather.......useless. There really wasn't much of a budget for anything beyond basic arts and crafts supplies.
Sometime in early high school I stopped with the honors classes though; I didn't have plans for college at the time, and the advanced classes seemed to translate only to "more tedious homework/busywork plus summer reading," so I went down a notch (honors/
academic/general). No more summer reading seemed like a great deal - academic English covered the exact same books, but they were read
during the school year. At the time, that struck me as being much more efficient.
Later (as in several years after high school) I found out that the lower classes gave a lower total GPA score. Oh well.
