The thing with study is every individual goes into final exams, thinking & wanting to be top dog, or getting the highest bands/ranks.
Came across a Year 12 kid today , saying "I only want a Band 6"' standard for a Maths exam. He also happened to have said something "I want to get into a good uni". He was 6th ranked in his school in that particular subject out of 170 or thereabouts students in his school. Kind of hate that 'competitiveness' as It can make some people 'really' unlikeable. Wouldn't mind if he kept to it himself , rather than blurt it out to me. I have been in the workforce doing different jobs, I'd imagine it must be the same competitiveness to get into a 'Big 4' or a big company. (I wasn't good enough with alot of top-tier graduate entry jobs and changed alot from jobs to jobs)
One thing I will say, with high school, is you wanted to beat your cohort, you wanted to be the best ranked as possible. Heck, I didn't go to the best high school but I never got to feel that competitiveness/rivalry of other students at the school I was at........But in saying that, I feel I would have enjoyed the competitiveness of other students as it would have improved my standards. But in university, it was working together as a close group of friends to get the best marks as possible. Its a huge difference in my opinion. You will still see that happen alot in 1st year university where students wanted to outbeat each other but by the time 2nd year approaches there is less of that competitive rivalry and you want to help/network with each other to successful careers/pathways.( It's something that I wasn't too good at: 'the social aspect of university')
