One situation in which I had a growth mindset was sophomore year of high school when I took algebra 2. Before this, I did not do so well in Algebra 1 in 8th grade so at first I was worried about not doing well again. But after realizing that it was a totally different class, a fresh start, I was able to get past my pre-conceived notion that I would not do well. This time around I was okay with not knowing everything and because of this, I did very well the second time around and passe with an A.
