I have some struggle in statistics. In university, I had to take some remedials for statistics: descriptive and inferential, because of bad score (although passed).
But I found myself to study on my own without any homework back in elementary schools. So I guess that I am pretty interested in math to some extent. The topic I was enthusiastic in was arithmetics: addition, substraction, multiplication, division, fractions, decimals, mixed fractions, etc. I was selected by the school I attended as one of their representative in a local competition. I was selected twice, for two consecutive years although I have never proceeded to the next phase. I was not informed about the level of the competition: whether it was a village, sub district, municipality, provincial level.
in high school,other students was selected. I feel that it was "a downturn" for me, since it was me who was selected in elementary school, not others.
I don't like the school that I attended select solely by their own criteria, who want to participate to the high school pre Olympiad competition ; not asking voluntarily who are willing to participate. Had the later been the policy, I could have registered my name for the competition. However, The student selected did not pass: pre olympiad, hence she did not proceed to the next phase of pre olympiad.
But I have tested my memory checking whether I could still retain memory of mathematics, by shutting off any source: google, books. Some formula come up in my mind rather easily: like the two dimensional structure area, volume of 3D structure that I was taught in elementary schools, more than two decades ago. I found also I still retain the memory of quadratic equation functions= x1,x2=minus b plus minus the root of squared b minus 4ac divided by 2a that i was taught in sometime in between 7th-9th grade.
Btw, I think It was rather crazy to select a student who was not asked whether she were willing to take part or not; she was selected because she was top class rank, whereas class ranking, is based on the sum of overall subjects taught; not only math. By the way, is statistics one of the topic of math or an entirely a separate discipline?
