level 3 advice + help!!

hi guys, i was just looking for some advice for the upcoming level 3 year. this year is probably the most important for me as i’m trying to get into UOA or UOO for health science/biomed or even convert into atar to go to aus!!

i am taking three sciences, calc and english and i would say im a decent student but the marking of the level 2 exams have sort of knocked down my confidence so i’m having mixed emotions (i did manage to gain excellence endorsed at level 2 overall though).

how should i go about this year without burning out? i am also a student athlete and have a leadership role so im fairly busy but i want to be able to achieve top notch results in everything which sounds unrealistic but i pretty much HAVE to. i have also been reviewing some stuff that we cover this year to atleast familiarise myself with the content but nothing too flashy. pls help :,((
