yeah ur right, it's kind of bad when an 99.95 student gets a fail or credit in uni...
How you perform in school to some extent doesn't reflect how you perform in uni.
congrats :)
I got similiar marks to u as well!
task 1 - 70/70
task 2- 59/60
task 3- 70/70
task 4- 45/45
do u think I could state rank??? (i go to a top 10 ranked school)
I know a guy who did his hsc in 2012 and got an atar of 96.5 with standard english and 2 unit maths.
so just do subjects u are good or have a interest in them. imo don't choose subjects based on scaling.
good luck and all the best :)
